ariaMultiSelectable property of the
ElementInternals 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.
Setting aria attributes on
ElementInternals allows default semantics to be defined on a custom element. These may be overwritten by author-defined attributes, but ensure that default semantics are retained should the author delete those attributes, or fail to add them at all. For more information see the Accessibility Object Model explainer.
let ariaMultiSelectable = ElementInternals.ariaMultiSelectable; ElementInternals.ariaMultiSelectable = ariaMultiSelectable;
DOMString with one of the following values:
- More than one item may be selected at a time.
- Only one item may be selected.
In this example the value of
ariaMultiSelectable is set to "true".
this.internals_.ariaMultiSelectable = "true";
