Hi,
At
https://issues.apache.org/jira/browse/OFBIZ-4913 we fixed few related (minor) issues. But we are not sure they are the only ones.
I just checked the main menu items applications on trunk demo using the Tomahawk theme, they are all "correct".
There is 17 applications with sub menus, when you get a chance please check some of them and report in the Jira
This way we should be able to close the case, without having to create a search tool.
Thanks for your help
Jacques
