jscookMenu submenu hidden by a div

Hi,I use a tomahawk 1.1.5 jscookMenu but I have a problem. The submenu is hidden by a div with IE. It works with Firefox. If someone could help me it would be great.

What is the z-index of the div and are there any <select> elements in the div.

There is just a div. In this div there is an image added by javascript. The menu is over the div with Firefox. I don't know exactly what is the z-index. I will search. I work with ArcGIS Server and this is the ESRI code which add the image (the map).
