I have a RadPanelBar that I am trying to display with the following conditions:
The first RadPanelItem needs to have a fixed height and a scrollbar when the content of the item exceeds the fixed height.
The second RadPanelItem needs to have one of its sub items replaced with a RadMenu that pops out to the side.

Using the information I have found on the this web site, I have created a sample web site (which I am not able to attach). The problem is that I have only been able to meet one goal at a time. In order to have the menu appear correctly, it is necessary to uncomment the <style> tag in the .aspx document so that the css statement "overflow: visible !important;" is applied to the content. However, when I do this, the content of the first RadPanelItem then overflows and overwrites the content of following RadPanelItems. Is there any way to have the content of the first RadPanelItem either ignore the overflow command or, failing that, override it?

I am using the latest Telerik release.

Since I am not able to attach my sample web site, I will paste some relevant fragments:
WebForm1.aspx:

Hi Andy,

I would suggest that you use the following css styles that work just fine in all versions of IE and Chrome. However, there is a limitation of this approach and it does not work correctly in FireFox only.

<style type="text/css">

RadPanelBar,

.RadPanelBar div.rpSlide,

.RadPanelBar ul.rpGroup,

.RadPanelBar li.rpItem /*, .RadPanelBar .rpTemplate*/

{

overflow: visible;

}

div.RadPanelBar .rpLevel1 .rpItem

{

padding:0;

}

* html .RadPanelBar .RadMenu ul.rmRootGroup

{

zoom: 1;

}

div.RadMenu .rmRootGroup

{

border: 0;

}

div.RadMenu .rmLink

{

float: none;

}

.NoOverflow,

.NoOverflow .RadPanelBar,

.NoOverflow .rpLevel1,

.NoOverflow .rpExpanded,

.NoOverflow .rpGroup,

.NoOverflow .rpItem /*, .RadPanelBar .rpTemplate*/

{

overflow: scroll !important;

}

</style>
