Drop down menu on a frame

[liunx]

I want to keep a drop down menu on a frame on the top of a page which remains visible always even when the user scrolls down. I want to know how to do this. I have doubts regarding the top frame's length. Should it be big enough to accomodate the expanded drop down menu? I request help from all you wizards.<!--content-->If you are talking about drop down list box then you don't have to because list box will have visibility on top of frames,on the other hand if you are talking about menus ( drop down) using css and javascript then yes you will have to leave the enough room for menu to be visible when unfolded, so that its not behind the frame.<br />
<br />
Cheers<br />
