Framework7 - Accordion

Description

The accordion is a graphical control element displayed as a stacked list of items. Each accordion can be expanded or stretched to reveal the content associated with that accordion.

Collapsible Layout

When you are using single separate collapsible element, you need to omit the accordion-list wrapper element.

Following is a structure of collapsible layout −

<!-- Single collapsible element ------>
<div class = "accordion-item">
   <div class = "accordion-item-toggle"></div>
   <div class = "accordion-item-content"></div>
</div>

<!-- Separate collapsible element -->
<div class = "accordion-item">
   <div class = "accordion-item-toggle"></div>
   <div class = "accordion-item-content"></div>
</div>

The following classes are used for accordion in Framework7 −
