+		 * * `_disabled` - a boolean indicating if this action should be disabled
+		 * * `label` - a string - the name of the action (could be a function returning a string)
+		 * * `title` - a string - an optional tooltip for the item
+		 * * `action` - a function to be executed if this item is chosen, the function will receive 
+		 * * `icon` - a string, can be a path to an icon or a className, if using an image that is in the current directory use a `./` prefix, otherwise it will be detected as a class
+		 * * `shortcut` - keyCode which will trigger the action if the menu is open (for example `113` for rename, which equals F2)
+		 * * `shortcut_label` - shortcut label (like for example `F2` for rename)
+		 * * `submenu` - an object with the same structure as $.jstree.defaults.contextmenu.items which can be used to create a submenu - each key will be rendered as a separate option in a submenu that will appear once the current item is hovered
