Information

This menu is aimed at all IE6 users who are having problems when using dropdown menus over 'form select boxes' where the select box is always on top no matter what z-index is used.

All other browsers will display correctly without this fix.

Based on the previous menu Professioanl menu #8 but using a very small 4 line javascript routine that takes all the hard work of styling each iframe with a width and height.

All that is necessay is to add the <iframe></iframe> after each <table><tr><td> and let the javascript work out the width and height for you based on the width and height of the following <ul>.

The only styling required is to position the <iframe> off screen when not required and on screen with the same 'top' and 'left' position as the following <ul> when that <ul> is made visible.

The javascript routine does nothing in all other browsers and is placed in the html just after the menu.

Tested in IE6, IE7, Firefox, Safari and Opera.
