Signal ID
Connect to ShowOptionMenu signal.
This signal is emitted when a select element in web_view needs to display a dropdown menu. This signal can be used to show a custom menu, using menu to get the details of all items that should be displayed. The area of the element in the #WebKitWebView is given as rectangle parameter, it can be used to position the menu. To handle this signal asynchronously you should keep a ref of the menu.
The default signal handler will pop up a #GtkMenu.
