# Collapse Menu

Collapse menus are typically used for navigation to different pages or sections.

A collapse menu contains 3 parts:

1. Title container
2. Arrow icon to collapse and expand the menu (on the right)
3. Menu content

You can customize all three parts. For example, in menu content, you can add a [Clickable](/app-builder/app-construction/elements/web-elements/clickable.md) with [Text](/app-builder/app-construction/elements/web-elements/text.md) inside, and set an interaction on the clickable to navigate to a different page.

## Properties

**Group ID:** If you have multiple collapse menus, group them together by Group ID. To group elements, give them the same ID.

**Single Collapse:** If you have grouped collapsed menus by Group ID, turning on Single Collapse ensures that only one collapse menu will be open at a time.

**Default Expand:** When on, the collapse menu will be expanded by default.

See [Tooltip](/app-builder/app-construction/elements/tooltip.md) for tooltip configurations.

## Supported Events
