The tab actions menu is a dropdown menu in the tab title bar. The menu items listed in the menu allow actions specific to the tab to be performed.
The items support opening UIM pages in the content area of a tab, or alternatively opening a modal dialog to perform some action - these are identified by an ellipses (...). Additionally, it is possible to download a file directly from a menu item.
The tab actions menu also supports the ability to dynamically hide/show and enable/disable items in the menu. Refer to User Interface Element 5 of Tabs for an example of a tab actions menu configured in an application. The menu items that are dynamically hidden are disabled in the menu.
