`selectedcontent`

Comments -

The `selectedcontent` element is meant to be declared as a child of the `button` part of a custom styled `select` element. - As the `button` part is meant to be treated as inert, the `selectedcontent` element will commonly be treated as inert, as well.

+

The `selectedcontent` element is a declarable child of the `button` part of a custom styled `select` element. + The `button` part of the `select` element's anatomy, and thus the `selectedcontent` element descendant, are inert.

+

+ The text equivalent computation of the subtree of the `selectedcontent` + element participates in the calculation of the `select` element's accessible value. +

- As the parent `button` element to the `selectedcontent` element is meant to be treated as inert, any use of global HTML or ARIA attributes, or attributes specific to the `selectedcontent` element would not be exposed to the user agent's accessibility API. + As part of the anatomy of a customized `select` element, the ancestor `button` element to the `selectedcontent` element is inert, any use of global HTML or ARIA attributes, or attributes specific to the `selectedcontent` element are not to be exposed to the user agent's accessibility API.
