Ajax建议列表问题。

My "ajax suggestion list" is getting hide behind "select menu", placed exactly below the text box calling ajax functionality. However its works perfectly in other browser but doesn't work with IE 6.0. Please suggest any solution. Also i already off the autocomplete feature for that text box but some time it works, sometime doesn't. Is there any permanent solution for this problem without disabling this feature through browser control panel.My "ajax suggestion list" is getting hide behin
