I am trying to create a 3 level menu where all the 3 layers are horizontal. If i hover over a item which has sub menu then the 2nd or 3 layer should appear respectively. Also if i click on 1st level menu item(having sub menu item) then 2nd level should stay. Similarly if i click on 2nd level menu item which has sub menu item then both 2nd and 3rd level menu's should stay.Can someone please help me in creating this kind of menu structure. Thanking in advance.
