You have just finished creating or installing a killer CSS Drop menu for your website. There is only one problem, in IE6 the menu disappears where HTML form elements and Flash layers appear. Form elements in IE will always cover DHTML layers. That means if you have a DIV that pops up or floats on the page and it crosses with a form element such as the common SELECT box, the form element will bleed through the CSS menu no matter what zIndex you have set. An example of this happening could be seen a Hiveminds.co.uk if not for the fix used.
