I have an page and it is published in a Portal and the Portal has dropdown menus.  When I view it in IE, the menu dropdown behind the page, but when I view it in Firefox it displays correctly.

Any idea why, what to look for???

Thank you!

    What to look for:

    IE handles z-index in odd ways. Generally, you need to tell IE how elements relate to one another first, then set z-index. In other words, check that both the menu <li>s and the element that is covering the <li>s have a position defined (like position:relative). Then set the z-index on the menu to bring it forward. You might even want to put the covering element at z-index:-1.

    Well then, it's time to tweak the css and add some z-indexes and positioning. You can do this best on-the-fly with Firebug in Firefox but since the problem is in IE, you can use their developer tools (yuk!). Once you know what fixes are required you can go back to the aspx pages and add the necessary css.

    Alternately, you can post your "view source" of the rendered page here as @meeran03 suggested and someone will help you get it working in IE.
