JAVASCRIPT: Layer vs. listbox problem ...

[bogu]

Hi there; simple question ... I have a layer that, when extended, appears under the dropdown listbox.

Is there any suggestion on how to make it appear overtop?

And does anyone know of a tutorial or something like yahoo mail or gmail have for the address book, when you start enter the email address to witch u want to send an email a layer appear with the all email addresses from your address book that contains what u entered into that field?

Thanks, any help is real appreciated …

You do this with the CSS z-index property. The element in question must be absolutely positioned for this property to have effect in IE.

By "A layer", do you mean an absolutely positioned element?

In some browsers, native widgets are used, which stops elements going over them - this includes <select> elements in some versions of MSIE.

There is no fix. Consider using radio buttons instead, which I think are not natively rendered in recent version of MSIE, hence respect z-index properly.

I think that all HTML elements are rendered in Mozilla and IE7 + , but not IE6 and below. Not sure about other browsers.

Yes.

Is sad for this IE bug; because of this lots of people are refusing to use layers (absolutely positioned elements) and u cand do lots of nice things...

The best solution if to make the layer not appear near a list box...

I know that is a work around for this bug by hide the elements if it appears under a layer but I dont know how I can determine wich elements are under my layer and witch are not.

Can't you put a containing div element around the area where your layer will show up. Then when your new layer shows up, just put:
document.getElementById('containingDiv').style.visibility='hidden';
and wham! it's hidden the elements under the div!!

The layer will be random size, so I want the layer script to be independent and should not depend where I show it on the page...

The layer size won't matter.... as long as the layer is around the elements you want to hide, the size won't matter.
