Easy question first:
You can change the color of the hover…but the change will effect all of the menu item hovers.
Goto ja.moomenu.css line 135 and modify
background: #00b0db none repeat scroll 0 0;
As for moving the 3rd level menu item…
Goto ja.moomenu.css line 40
#ja-cssmenu li ul ul {
margin:-2em 0 0 15em;
}
In the above code the “-2em” controls the position of the 3rd tier menus left and right position…and the “15em” controls the up and down positioning.
If you wanted the 3rd tier to be exactly to the right of the 2nd tier with no overlap then the code would read:
margin: -2.5em 0 0 16em;
Play around with those two numbers to get the different effects.
Have fun.
