how to do this style slide navigation?
<p>eg: the main navigation is "one","two","three","four".
the child navigation is "welcome to our site" this navigation under the main nav "one".
the "two1","two2","two3","two4" belongs two,
the "three1","three2 belogs to main nav "three"</p>

<p>now, i want to get when the mouse hover on one, the  "welcome to our site" shows in a blcok.the block only shows the "one" child nav. when hover on the two, the  "two1","two2","two3","two4" shows in the same block.the block only shows the "two" child nav
then hover on the "three". the same as the above. </p>

<p>could i use the jquery or javascript to get this?</p>
