This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
Summary
The HTML <menuitem>
element represents a command that a user is able to invoke through a popup menu. This includes context menus, as well as menus that might be attached to a menu button.
A command can either be defined explicitly, with a textual label and optional icon to describe its appearance, or alternatively as an indirect command whose behavior is defined by a separate element. Commands can also optionally include a checkbox or be grouped to share radio buttons. (Menu items for indirect commands gain checkboxes or radio buttons when defined against elements <input type="checkbox">
and <input type="radio">
.)
