Overview

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

JSON array binding

Nested accordions

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


Accordion navigation menu

The ASP.NET Core 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.

Developer-friendly APIs

State persistence

  • 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.
