web site menu needlessly jumps around
Go to a page like
Examine the menu on the left. Think of what you want to put your pointer on, and move your pointer there. Because your mouse-pointer is there, the location of things near it is different! Where you wanted to click changed because you tried to click. That's annoying, and it gives no new functionality. You may wish to emphasize what the user is going to select if they click, but there are better ways than changing the layout of the menu to do it.
I suggest making the text a different color. That's almost always safe, and it's what people expect.
