We had our Custom Menu in 7.1. We cloned the Dev and tried to upgrade it to 8.0.
By now, everything looks fine. Except that We are not able to place our custom Menu on 8.0. We are placing the menu file under Menu -> Congif but the menu doesnt appear. Has anybody tried to place a custom menu in 8.0.
Yes, in release 8 the menu system is different. The whole menu structure is in one file "menu.xml". We too had a customized menu structure in 7.5, we had to reimplement all customizations in this menu.xml. Copy&paste will not be enough though, as the xml-structure is not the same and because of MLU you need to use reference codes fro groups, access grants etc.
Sure, in conf/menus/ you should have only two files menu.xml and menu.xsd, the rest that may be still in there should be removed (or zipped up like on the screenshot). Then you need to edit the xml file (and optionally a custom properties file if you are going for MLU). It's very helpfull to have an appropriate xml editor and creating your own structure is a little bit more work than it used to be, because you have to look up the reference codes for security groups, grants etc.
