Bind Accordion to Data

You can display Accordion items from the items array or a dataSource. If you use the items array, specify the title and text properties.

Configure Item Selection and Collapsibility

Enable the multiple property to allow users to select multiple panels. Use the selectedItems array to store selected items. Toggle the "Multiple enabled" checkbox in the Options demo section to see how it affects the selection.

If you want to allow users to close panels on click, set the collapsible property to true. Check the "Collapsible enabled" checkbox in the Options demo section to enable this feature.

Configure Animation

The animationDuration property allows you to specify the animation duration when users expand/collapse a panel. Use the "Animation duration" slider in the Options demo section to see how it affects the animation.

Customize Item Appearance

Use the itemTemplate and itemTitleTemplate properties to customize the panel appearance. If you use the items array, you can also specify the icon property.
