The FAQ/Accordion Block is an Information Banner that allows the user to add multiple "accordion groups" of Title and Description (or Question and Answer) to an interface that can be configured to expand and collapse in different ways.
You can find the block within the Banners / Information Banners section of the +Add Menu. Click or Drag & Drop to add it to your page.
The block can then be edited by clicking "Edit FAQ Accordion"
Add, Edit or Delete "According Groups" by clicking on their respective links within the above interface. You can also specify if the Accordion Block displays Collapsed or Expanded by default, or to have the first group expanded. There are also Behavior settings that determine how the accordion works when expanding each option: one at a time, or multiple.
