thank you Jimmy,
Tell you the truth that I don't know what you talking about when " set up mod_rewrite on your server to rewrite " and search on internet and it is scary.....
BUT I changed "#" to "../index.php"
<li class="parent"><span><span><a href="#">pants</a></span></span>
and looks Ok but when I click on button (main) then shows the hover color again....
How can I void this kind of problem for next time, because i never had it.
again thanks for your help
