Proposal: Add possibilty to assign custom CSS classes to containers in Form Builder
This issue intends to achieve more control and flexibility in styling the frontend appearance of form builder forms. To achieve this we suggest to add the possibility of assigning custom CSS classes to containers in the configuration backend / GUI of Form Builder.
This is meant to be an addition to the Form Builder Roadmap.
Currently it is possible to select a predefined CSS class from the 'style' dropdown menu ("Panel Pane"). When this style is selected, an additional class is added to the div container ("af-container-style-pane").
We propose to give users the possibilty to add custom CSS classes to form builder containers in a new input (text) field to allow more control and flexibility in styling the frontend appearance of form builder forms.
Some major parts of the relevant code seems to be in these files:
