Turn multi layer dropdown from clicking to hoverable - html

Question

I currently have a multi layered dropdown that goes up to three lists. I am trying to have all the lists that show up automated by hover. This is because my intention is to have an href link, right now the link only works on the third dropdown list because the click the others before is used to display the next dropdown.
i tried to add :hover in the css of the classes dropdown-menu and dropdown submenu with "display: block;" but this is not functioning and the lists still shows only when clicked.
