I am recently working on a website with drop down menus. When I add another layer to the page, the drop down menus are below the new layer therefore hiding them to the user. I tried using the z-index numbers but they don't seem to be working. Any help would be greatly appreciated.

Thanks,
Tara

Tara, it's not possible to help without seeing your code.  I can, however, 
GUESS what might be happening.  I'm thinking that the submenus (with their 
z-index) are contained within a parent menu container (with its z-index). 
When you have a nested situation like this, the descendent z-idices are all 
only effective within the context of the parent z-index.  In other words, if 
the parent's z-index is 1, then a submenu with a z-index of 5000 will be 
higher than any other submenu with a z-index less than 5000, but will still 
only be considered to have a z-index of 1 vis-a-vis the page itself.  Thus, 
adjusting the submenu z-index values will only affect the behavior inside 
the parent.  To move the menu 'closer to the top', you'd have to adjust the 
parent's z-index.

Make sense?  It's completely hypothetical, though.

Murray, can I ask that if you ask to see someone's code, you remind them of how to post it? Just plonking it into a post wreaks havoc with the forum layout, and it doesn't show up anyway.

I suspect Murray means we'd need to see a link to the page in question. There's no special instruction needed for how to post a link.

Otherwise we are blind.

Well, no - if he's reading via a newsreader, it may well be that posting code is fine for him. I suspect he means what he says.

Either would have been OK, but of course, Jim is correct in that the best 
solution is to actually see the page 'in extremis' as it were.... 8)

However, I will remember to remind folks how to do this - thanks for your 
suggestion.  With more than just a few lines, though, it's quite 
impractical....

Of course that's best - I was just a bit nervous about you unwittingly encouraging people to create havoc in the forum. We really, really don't want raw code in here.

Of course, there are times when a screenshot is pretty useful ;)

Screenshots of code are marginally useful anytime. and screenshots of layout 
issues are not useful at all in diagnosing the problem.  It only shows us 
the result not the "why".

Just teasing you Murray - you say tomatoes raw code, I say tomatoes posted images.
