The HTML aria-haspopup attribute
The aria-haspopup attribute indicates that a control opens a popup, and what type it is. Values: menu, listbox, tree, grid, dialog, or true (which means menu). Use false or omit when there is no popup.
Overview
The aria-haspopup attribute indicates that an element triggers a popup such as a menu, listbox or dialog.
It is a widget property: a declaration about the widget that is normally set once, rather than a state that changes as the user interacts. Because ARIA does nothing on its own, keep it accurate and update it in JavaScript if the widget's behavior does change; a stale value is worse than none. And wherever a native element already expresses the same thing (a <textarea> for multi-line input, the required or readonly attribute, a native multiple select), use that instead.
Like all ARIA, aria-haspopup changes only the accessibility tree (what assistive technology perceives), never the element's behavior or appearance. The first rule of ARIA applies: if a native HTML element or attribute conveys this, use that instead, and only reach for ARIA when nothing native fits.
Syntax
<button aria-haspopup="menu" aria-expanded="false">Options</button>Values
| Value |
|---|
| false | true | menu | listbox | tree | grid | dialog |
Example
<button aria-haspopup="listbox" aria-expanded="false" aria-controls="lb">Country</button>Best practices
- Follow the first rule of ARIA: use a native HTML element or attribute that conveys this where one exists, rather than adding ARIA.
- Set it to match the behavior you actually implement, and change it only if that behavior changes.
- Use the matching native attribute where one exists (
required,readonly,multiple) instead of the ARIA version. - Set it only on an element whose role actually supports this property.
