    Experimental Example of Tabs with Action Buttons

    + +
    +

    About This Experimental Example

    + +

    + This is an experimental implementation of the draft specification of the aria-actions attribute. + The aria-actions property enables an element to reference another interactive element that can be activated to perform an action on the referencing element. + In this example, each tab element references a menu button that opens a menu of actions that apply to the referencing tab. + The relationship provided by aria-actions enables an assistive technology to both communicate the availability of the action button and provide a command for activating the button while focus is on the tab. +

    +

    + The below example demonstrates a tabs widget that implements the Tabs Pattern. + In this example, a panel is displayed when users activate its tab with either Space, Enter, or a mouse click. + So, for keyboard users, activating a tab requires two steps: 1) focus the tab, and 2) activate the tab. + This two-step process is referred to as manual activation. + Manual activation of tabs is recommended unless panels can be displayed instantly, i.e., all the panel content is present in the DOM. + For additional guidance, see Deciding When to Make Selection Automatically Follow Focus. +

    +

    + This example also demonstrates how to provide buttons that provide contextual actions for the tab. + Each tab has an associated context actions menu button. + The menu button is referenced by aria-actions, which enables it to be activated by an assistive technology user while focus is on the tab. +
