Active Item in Perspective Menu Tree

Is there a way to set up an element state for the Menu Tree when that window is in focus? I would like to have 3 element states, inactive, hover, and active similar to this screenshot. 58%20PM
But the “active” element state in the style class only works when the menu link is actively being clicked on, then it goes back to an inactive state.
Is there a different element state I need to be using?
