Accordion
Documentation
The Accordion component contains several panels displayed one under another. These panels can be collapsed or expanded by a user, which makes this component very useful for presenting information in a limited amount of space.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
