DevExtreme Angular - Overview

The Accordion widget contains several panels displayed one under another. These panels can be collapsed or expanded by an end user, which makes this widget very useful for presenting information in a limited amount of space.

The following code adds a simple Accordion to your page. Note that each data source object contains the title field, whose value goes to the title of the panel.
