We can use the GlideMenu class to customize the options available in the form header context menu through the client scripts. The g_item object refers to the GlideMenuItem class.

The following are some examples of functions available in the GlideMenu class:

• voidg_menu.clearImage: This method can be used to specify which item will have its image removed from the display:

        g_menu.clearImage(g_item); 

• void setDisabled: This method can be used to mark a menu item as disabled:

        g_menu.setDisabled(g_item)
