Element: ariaMultiSelectable property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since October 2023.

The ariaMultiSelectable property of the Element interface reflects the value of the aria-multiselectable attribute, which indicates that the user may select more than one item from the current selectable descendants.

Note: Where possible use an HTML <select> element as this has built in semantics and does not require ARIA attributes.

Value

A string with one of the following values:

"true": More than one item may be selected at a time.
"false": Only one item may be selected.

Examples

In this example the aria-multiselectable attribute on the element with an ID of listbox1 is set to "true" indicating that this input accepts multiple selected items. Using ariaMultiSelectable we update the value to "false".

html

<div
  role="listbox"
  tabindex="0"
  id="listbox1"

  aria-labelledby="listbox1label"
  aria-activedescendant="listbox1-1">
  <div role="option" id="listbox1-1" class="selected" aria-selected="true">
    Green
  </div>
  <div role="option" id="listbox1-2">Orange</div>
  <div role="option" id="listbox1-3">Red</div>
</div>

let el = document.getElementById("listbox1");
console.log(el.ariaMultiSelectable); // "true"
el.ariaMultiSelectable = "false";
console.log(el.ariaMultiSelectable); // "false"
