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.
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.
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".
<div
role="listbox"
tabindex="0"
id="listbox1"
aria-multiselectable="true"
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"
