This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
tabStop property of the
Element interface returns a
Boolean indicating if the element can receive input focus via the tab key. If the specified element is a shadow host tab navigation is delegated to its children.
This property was proposed to add tab functionality for Custom Elements. While with the existing
tabIndex property, it is required to specify an order for the element to become tabbable. The
tabStop property would decouple the tabbable property from the tab index. After feedback, this property was removed from the design doc and replaced by
var isTabStop = element.tabStop; element.tabStop = (true|false);
