Can't reproduce problem. See screenshot-1. Maybe the cause is not the scrollable div, but the portlet environment? Need to investigate it further in a portlet environment.

Can't reproduce problem in the portlet environment either. See screenshot-2. Should ask user to provide a sample app. with the problem.

I guess the real problem is when the scrollable div has smaller height like the one in the screenshot I attached, then the menu bar is rendered regardless of relative position. This is not a problem when this item has the same relative and absolute position.

As can be seen in screenshot-3, still can't reproduce problem after making the div height much smaller. Really need a sample app. from the user to proceed any further.

Attached a portlets war file: c-s-portlets.war. You can run it to see if the problem shows up on your machine. Use liferay-portal-tomcat-6.0-4.4.2 and run the tree portlet.

We need a succinct test case that reproduces this problem before it can be pursued further.

Test case intended for Liferay 4.4.1

Can't deploy the test app. successfully. See screenshot-4 for the errors.

Had to merge code into component showcase portlets. Portlets then deployed successfully and problem was reproduced. See screenshot-5.

Yip,

Does the menu positioning fix for ICE-3620 resolve this issue also? Please confirm.

Nothing to do with component rendering. Caused by CSS in the complicated layout (menu within table within tree) and portlet environment. One improvement I came up with looks like this:

<ice:portlet>
<ice:outputStyle href="/xmlhttp/css/rime/rime-portlet.css"/>
<ice:outputStyle href="./css/showcase_style.css"/>
<style>
.portlet-menu-cascade-item

</style>
<ice:form id="treeform">
<!-- rest same as in the sample app. source -->
</ice:form>
</ice:portlet>

See the attached screeshot for the results.
