Feature #84133
Updated by Ralf Zimmermann over 6 years ago
Variants allow you to change properties of a form element.
Variants can be made under conditions.
This makes it possible to manipulate form element values, validator options, and finisher options based on conditions.
The allows among other things:
* translation of form element values depending on the frontend language
* set and remove validators of one form element depending on the value of another form element
* hide entire pages depending on the value of a form element
* set finisher values depending on the value of a form element
* hiding a form element in certain finishers and on the summary page
* and much more
This feature implements variants for frontend rendering and the ability to define variants in the formDefinition.
The implementation to define variants in the form editor is done in a separate patchset.
