[richfaces-issues] [JBoss JIRA] (RF-12287) Dropdown menues hidden by other elements in IE 8

[Brian Leathem (JIRA)]

    [ https://issues.jboss.org/browse/RF-12287?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12739063#comment-12739063 ] 

Brian Leathem commented on RF-12287:
------------------------------------

I found the answer in [this blog|http://blog.team-noir.net/2010/05/how-to-use-position-absolute-and-z-index-with-internet-explorer-7-and-nested-containers/] whereby we have to set the z-index in both the popup element, and it's parent element.

Setting the _z-index_ for _.rf-ddm-lbl_ and _.rf-ddm-pos_ resolves both RF-12287 and this issue.
