as shown in figure 1, the on-select event of iview"s navigation menu is useful only if the drop-down suboption is selected. 
 but what I need now is to trigger my custom click event when I click on the title "my assets", such as  @ click= "capital"  in figure 2, but it doesn"t work. 
 I try to wrap a  span  tag around  < Submenu/ > , and bind click to the  span  tag. It still doesn"t work
