The JavaScript Accordion is a container-based control with vertically collapsible panels (vertical accordion) and stacked headers that expand or collapse one or more panels at a time within the available space.

Expand and collapse

The JavaScript Accordion control allows you to customize the expand and collapse actions.

Expand mode

A single panel or multiple panels can expand or collapse (panel toggle) at a time by clicking the panel header (interactions) or programmatically.

Collapsible mode

Collapse all the panels at once. With customization options, a specific panel is set to be in an open state while the rest of the panels are collapsed.

Accordion templates

The JavaScript Accordion control allows you to customize the header and content panel appearance using given HTML elements.

JS Accordion in data binding

JSON array binding

The JavaScript Accordion control can be rendered based on a JSON array collection of properties such as headers and content. Data binding can be achieved by an array collection of items.

Nested accordions

Add nested levels of the collapsible panel within the parent accordion.

Accordion navigation menu

The HTML5 Accordion control can use a nested vertical (hierarchical) navigation menu with links, including external links, in the accordion header.

Icon support

Add prefix icons or images to the panel header. The default expand and collapse icon used in the header is customizable.

HTML5 Accordion in touch mode

Responsive accordion

The JavaScript Accordion control adapts responsively in devices based on the available space for modern web and mobile applications.

Dynamic AJAX content

The JS Accordion allows you to load external content dynamically to a panel using the AJAX library.

Accordion JavaScript with dynamic loaded content through AJAX

Accordion JavaScript with animated panels


JavaScript collapsible panels support several types of built-in fancy animation for panel expanding and collapsing actions. Animation behavior is customizable.

Developer-friendly APIs

Developers can control the appearance and behavior of accordions using a rich set of APIs.

State persistence

During browser navigation, the expanded or collapsed state of an accordion persists.


  • Fully supports WAI-ARIA accessibility that helps the accordion control be accessed by on-screen readers and assistive devices.
  • Follows WAI-ARIA Best Practices for implementing keyboard interaction.
  • Designed the UI element visuals such as foreground color, background color, line spacing, text and images based on WCG 2.0 standard.

Built-in themes

The HTML5 Accordion control is shipped with several built-in themes such as Material, Bootstrap, Fabric (Office 365), Tailwind CSS, and High Contrast.

Users can customize any one of these built-in themes or create new themes by either simply overriding SASS variables or using our Theme Studio application.

Other supported frameworks

The Accordion component is also available in Blazor, React, Angular, and Vue frameworks. Check out the different Accordion platforms from the links below,
