I had a problem with the drop-down menu displaying behind a div, but that is fixed, now it is being overlapped by the text of another div:
alt text http://cl.ly/d9bd4af6e533bbce8cdf/content
This only happens in IE7, I imagine it does in IE6 as well, but did not test in IE6.
I set the z-index of the div's it drop-downs over to z-index:1; and the z-index of the drop-down is set to 2.
Works fine in google chrome and firefox.
Any help is appreciated.
Try to add
position: relative;
To your "Activity Wall" div.
z-index attribute won't work if your selector isn't positionned.
