Combo's drop-down list cutoff at iframe boundary in Firefox

Works perfectly in IE but in Firefox if the combo is near the base of an iframe the drop-down list is cutoff. In IE the list extends over the iframe boundary - any way I can sort this in Firefox ??

(Same thing occurs with combos in a grid column.)

Any help much appreciated.

I am afraid the only solution is not using iframe. The popup in IE is implemented with popup window object (IE-specific), while it is just normal DIV tag in FF and other browsers. The IE popup window can extend outside the browser/iframe window but the DIV is visible only withing the current frame/window borders.

Doh! That was my guess - thanks for confirming.

Within a grid is there any way to automatically disable combos nearer the base, i.e. depending on scroll position. Somewhat unsure of the scroll events available.

Thanks.

Scrolling -

grid.onScrollTopChanged = function(verticalOffsetInPx){...};

Current row -

grid.onCurrentRowChanged = function(rowIndex){};

Or, alternatively, you can just calculate the vertical position of the current cell or row element.
