If it is not installed you can export the document anyway but the example in the section about dynamic form elements will not appear in the output. \series bold insdljs.sty \series default is part of the \series bold acrotex \series default bundle available on CTAN. As the name suggests, the style files of the bundle produce pdf files which will work correctly \emph on only \emph default with Acrobat DC. \end_layout \end_inset \end_layout \begin_layout Standard By loading the module PDF \begin_inset space ~ \end_inset Form the whole document or a part of it can be made a PDF form. You can add all possible form elements like text fields buttons etc. This document describes how this is done. \end_layout \begin_layout Section Preparation \begin_inset CommandInset label LatexCommand label name "sec:Preparation" \end_inset \end_layout \begin_layout Standard At first load the module PDF \begin_inset space ~ \end_inset Form in the document settings of your file. To make the whole document a form, insert the environment \family sans Begin \begin_inset space ~ \end_inset PDF \begin_inset space ~ \end_inset Form \family default from \SpecialChar LyX 's dropdown menu at the beginning of the document. If only a part of the document should be a form, add \family sans Begin \begin_inset space ~ \end_inset PDF \begin_inset space ~ \end_inset Form \family default at the position where the form should start. \end_layout \begin_layout Standard \begin_inset Note Greyedout status open \begin_layout Plain Layout \series bold Note: \series default It is only possible to have one form in a PDF file! \end_layout \end_inset \end_layout \begin_layout Standard If the form data should be submitted to a server or the like, then you must specify the URL as parameter of the \family sans Begin \begin_inset space ~ \end_inset PDF \begin_inset space ~ \end_inset Form \family default environment. This is done by using the menu \family sans Insert\SpecialChar menuseparator PDF \begin_inset space ~ \end_inset Form \begin_inset space ~ \end_inset Parameters \family default . For example in this document the following was inserted to the parameter inset: \end_layout \begin_layout Standard \series bold action=mailto:forms@lyx.test?subject=The submitted PDF form, \begin_inset Newline newline \end_inset method=post \end_layout \begin_layout Standard This sends the form data as email to \emph on forms@lyx.test \emph default when the user presses the submit button. The email subject will be \begin_inset Quotes eld \end_inset The submitted PDF form \begin_inset Quotes erd \end_inset and the submit method is \series bold post \series default .

For more about submitting see sec. \begin_inset space \thinspace{} \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Submit-button" nolink "false" \end_inset . \end_layout \begin_layout Standard \begin_inset Newpage newpage \end_inset \end_layout \begin_layout Section Form elements \end_layout \begin_layout Standard There are 6 \begin_inset space ~ \end_inset possible elements in a PDF form: \end_layout \begin_layout Subsection Text field \end_layout \begin_layout Standard A text field is added by inserting the custom inset \family sans TextField \family default using the menu \family sans Insert\SpecialChar menuseparator Custom \begin_inset space ~ \end_inset Insets \family default . Write inside the inset the label for the text field that will be printed in the PDF output before the field. Here is an example: \begin_inset Newline newline \end_inset \begin_inset Flex TextField status open \begin_layout Plain Layout \begin_inset Argument 1 status open \begin_layout Plain Layout name=customer \end_layout \end_inset Enter your name here: \end_layout \end_inset \end_layout \begin_layout Standard You must also specify a name for text fields. To do this set the cursor into its \family sans Params \family default inset and insert the parameter \series bold name=customer \series default (where \series bold customer \series default is the field name). \end_layout \begin_layout Standard Using the same name for several text fields results in an automatic duplication of the inserted text. This is for example useful if the user should input a date that should appear at different places in the form. \begin_inset Newline newline \end_inset Here are 2 \begin_inset space ~ \end_inset fields as example: Fill one and see that the other one will be filled automatically when you click outside of the field: \begin_inset Newline newline \end_inset \begin_inset Flex TextField status open \begin_layout Plain Layout \begin_inset Argument 1 status open \begin_layout Plain Layout name=identic \end_layout \end_inset \end_layout \end_inset \begin_inset Newline newline \end_inset \begin_inset Flex TextField status open \begin_layout Plain Layout \begin_inset Argument 1 status open \begin_layout Plain Layout name=identic \end_layout \end_inset \end_layout \end_inset \end_layout \begin_layout Standard \begin_inset Note Greyedout status open \begin_layout Plain Layout \series bold Note: \series default Special characters should be avoided in element names. \end_layout \end_inset \end_layout \begin_layout Standard All form fields can be customized by adding parameters. \end_layout \begin_layout Standard Here is a customized multiline text field with a width of 60 \begin_inset space \thinspace{} \end_inset % of the text width, 3 \begin_inset space \thinspace{} \end_inset cm height and a proposed content: \begin_inset VSpace defskip \end_inset \begin_inset Newline newline \end_inset \begin_inset Flex TextField status open \begin_layout Plain Layout \begin_inset Argument 1 status open \begin_layout Plain Layout name=customer2, multiline, width=0.6 \backslash textwidth, height=3cm, value={proposed text} \end_layout \end_inset Enter your name here: \end_layout \end_inset \end_layout \begin_layout Standard \begin_inset Note Greyedout status open \begin_layout Plain Layout \series bold Note: \series default It is highly recommended to use a uniform layout of all fields in a form. See sec. \begin_inset space \thinspace{} \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Form-element-customization" nolink "false" \end_inset how this is done. \end_layout \end_inset \end_layout \begin_layout Subsection Check box \end_layout \begin_layout Standard A check box is added by inserting the custom inset \family sans CheckBox \family default . Write inside the inset the label for the box. Here is an example: \begin_inset Newline newline \end_inset \begin_inset Flex CheckBox status open \begin_layout Plain Layout \begin_inset Argument 1 status open \begin_layout Plain Layout name=age \end_layout \end_inset Are you older than 18 years? \end_layout \end_inset \end_layout \begin_layout Standard You must specify also for check boxes a name. Insert e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space \space{} \end_inset the parameter \series bold name=age \series default (where \series bold age \series default is the name) into the \family sans Params \family default inset. \end_layout \begin_layout Subsection Choice menu \end_layout \begin_layout Standard A choice menu is added by inserting the custom inset \family sans ChoiceMenu \family default . A label for the inset is added by using the menu \family sans Insert\SpecialChar menuseparator Label \family default . The different choices are inserted to the inset as comma-separated list. There are 3 \begin_inset space ~ \end_inset choice menu types: \end_layout \begin_layout Description Radio Only one choice can be selected \end_layout \begin_layout Description Combo The choices are listed in a combo box (dropdown list) but the user is allowed to input something that is not in the predefined list. \end_layout \begin_layout Description Popdown All choices are listed below each other. If the menu is not high enough a scroll bar is automatically added. \end_layout \begin_layout Standard To determine the choice menu type one uses the parameter \series bold radio \series default , \series bold combo \series default or \series bold popdown \series default . \end_layout \begin_layout Standard Here is an example for the radio type: \begin_inset VSpace defskip \end_inset \begin_inset Newline newline \end_inset \begin_inset Flex ChoiceMenu status open \begin_layout Plain Layout \begin_inset Argument 1 status open \begin_layout Plain Layout radio, name=radio \end_layout \end_inset male=m, female=f \begin_inset Argument 2 status open \begin_layout Plain Layout Sex: \end_layout \end_inset \end_layout \end_inset \end_layout \begin_layout Standard Here is an example for the combo type: \begin_inset VSpace defskip \end_inset \begin_inset Newline newline \end_inset \begin_inset Flex ChoiceMenu status open \begin_layout Plain Layout \begin_inset Argument 1 status open \begin_layout Plain Layout combo, name=combo \end_layout \end_inset Albania=Al, Armenia=Ar, Azerbaidschan=Az \begin_inset Argument 2 status open \begin_layout Plain Layout Country: \end_layout \end_inset \end_layout \end_inset \end_layout \begin_layout Standard Here is an example for the popdown type: \begin_inset VSpace defskip \end_inset \begin_inset Newline newline \end_inset \begin_inset Flex ChoiceMenu status open \begin_layout Plain Layout \begin_inset Argument 1 status open \begin_layout Plain Layout popdown, name=country \end_layout \end_inset Albania=Al, Armenia=Ar, Azerbaidschan=Az \begin_inset Argument 2 status open \begin_layout Plain Layout Country: \end_layout \end_inset \end_layout \end_inset \end_layout \begin_layout Standard You must also specify a name for choice menus. Insert for example the parameter \series bold name=country \series default (where \series bold country \series default is the name) into the \family sans Params \family default inset. \end_layout \begin_layout Standard It is recommended to add a short name for every choice to be able to access them and to know which one was chosen by the user. This is done by adding \series bold =name \series default behind each choice (where \series bold name \series default is the choice name). For example the radio type example contains this choice list: \series bold male=m, female=f \series default . If the user chose \begin_inset Quotes eld \end_inset male \begin_inset Quotes erd \end_inset you know that he chose the choice \begin_inset Quotes eld \end_inset m \begin_inset Quotes erd \end_inset . With the name you can also preset/propose e.g. \begin_inset space \space{} \end_inset the choice \begin_inset Quotes eld \end_inset male \begin_inset Quotes erd \end_inset by adding the parameter \series bold default=m \series default . Here is an example: \end_layout \begin_layout Standard \begin_inset Flex ChoiceMenu status open \begin_layout Plain Layout \begin_inset Argument 1 status open \begin_layout Plain Layout radio, name=sex, default=m \end_layout \end_inset male=m, female=f \begin_inset Argument 2 status open \begin_layout Plain Layout Sex: \end_layout \end_inset \end_layout \end_inset \end_layout \begin_layout Subsection Push button \end_layout \begin_layout Standard A push button is added by inserting the custom inset \family sans PushButton \family default . Write inside the inset the label for the button. Here is an example: \end_layout \begin_layout Standard \begin_inset Flex PushButton status open \begin_layout Plain Layout \begin_inset Argument 1 status open \begin_layout Plain Layout \end_layout \end_inset Don't click on this button or your fridge will be destroyed!!! \end_layout \end_inset \end_layout \begin_layout Standard The action that is triggered by pressing the button is specified by JavaScript code. To do this, add the parameter \series bold onclick={} \series default and insert the JavaScript code between the braces. For info about JavaScript, see its documentation, \begin_inset CommandInset citation LatexCommand cite key "JavaScript" literal "true" \end_inset . In the following example this JavaScript code was used: \begin_inset Newline newline \end_inset \series bold app.alert( \begin_inset ERT status collapsed \begin_layout Plain Layout " \end_layout \end_inset What the hell? Now you destroyed your fridge. \begin_inset Quotes eld \end_inset Congratulations. \begin_inset Quotes erd \end_inset \begin_inset ERT status collapsed \begin_layout Plain Layout " \end_layout \end_inset ) \end_layout \begin_layout Standard \begin_inset Flex PushButton status open \begin_layout Plain Layout \begin_inset Argument 1 status open \begin_layout Plain Layout onclick={app.alert( \begin_inset ERT status collapsed \begin_layout Plain Layout " \end_layout \end_inset What the hell?

Such a button is created by inserting a hyperlink as button text. Here is an example: \end_layout \begin_layout Standard \begin_inset Flex PushButton status open \begin_layout Plain Layout \begin_inset Argument 1 status open \begin_layout Plain Layout \end_layout \end_inset \begin_inset CommandInset href LatexCommand href name "Information how to fill out this form" target "https://wiki.lyx.org" literal "false" \end_inset \end_layout \end_inset \end_layout \begin_layout Standard To get rid of the predefined frame for weblinks add this to the additional options in the document settings under \family sans PDF \begin_inset space ~ \end_inset properties \family default : \end_layout \begin_layout Standard \series bold urlbordercolor={1 0 0} \end_layout \begin_layout Standard if your push button border color is red (the default), otherwise use the same color definition as for your push button border color. \end_layout \begin_layout Subsection Submit button \begin_inset CommandInset label LatexCommand label name "subsec:Submit-button" \end_inset \end_layout \begin_layout Standard A submit button is used to submit the form data to a server. It is added by inserting the custom inset \family sans SubmitButton \family default . The label for the button is written into the inset. Here is an example: \end_layout \begin_layout Standard \begin_inset Flex SubmitButton status open \begin_layout Plain Layout \begin_inset Argument 1 status open \begin_layout Plain Layout name=submit1 \end_layout \end_inset Send your data via email \end_layout \end_inset \end_layout \begin_layout Standard The submit button creates a forms data format (FDF) file (file extension *.fdf) which is then submitted. The FDF file contains only the form data. They can later only be applied to a PDF form if all elements in the form have a name. \end_layout \begin_layout Standard \begin_inset Note Greyedout status open \begin_layout Plain Layout \series bold Note: \series default You can only use a submit button if you specified the submit method and a target in the inset \family sans PDF \begin_inset space ~ \end_inset Form \begin_inset space ~ \end_inset Parameters \family default ! See sec. \begin_inset space \thinspace{} \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Preparation" nolink "false" \end_inset for the description. If there are no specifications you will get \SpecialChar LaTeX errors. \end_layout \end_inset \end_layout \begin_layout Subsection Reset button \end_layout \begin_layout Standard A reset button is used to reset all form elements to the initial state. It is added by inserting the custom inset \family sans ResetButton \family default . The label for the button is written into the inset. Here is an example: \end_layout \begin_layout Standard \begin_inset Flex ResetButton status open \begin_layout Plain Layout \begin_inset Argument 1 status open \begin_layout Plain Layout name=reset1 \end_layout \end_inset Reset the form \end_layout \end_inset \end_layout \begin_layout Section Form element customization \begin_inset CommandInset label LatexCommand label name "sec:Form-element-customization" \end_inset \end_layout \begin_layout Standard Since all form elements should look uniform, one can determine their layout using the following styles: \end_layout \begin_layout Description Text \begin_inset space ~ \end_inset Field \begin_inset space ~ \end_inset Style \end_layout \begin_layout Description Check \begin_inset space ~ \end_inset Box \begin_inset space ~ \end_inset Style \end_layout \begin_layout Description List \begin_inset space ~ \end_inset Box \begin_inset space ~ \end_inset Style affects all choice menu types \end_layout \begin_layout Description Combo \begin_inset space ~ \end_inset Box \begin_inset space ~ \end_inset Style affects only the combo box style \end_layout \begin_layout Description Popdown \begin_inset space ~ \end_inset Box \begin_inset space ~ \end_inset Style affects only the popdown box style \end_layout \begin_layout Description Radio \begin_inset space ~ \end_inset Box \begin_inset space ~ \end_inset Style affects only the radio box style \end_layout \begin_layout Description Push \begin_inset space ~ \end_inset Button \begin_inset space ~ \end_inset Style \end_layout \begin_layout Description Submit \begin_inset space ~ \end_inset Button \begin_inset space ~ \end_inset Style \end_layout \begin_layout Description Reset \begin_inset space ~ \end_inset Button \begin_inset space ~ \end_inset Style \end_layout \begin_layout Standard The content of the styles is a comma-separated list of parameters.
