I am currently trying to set the button "use top navigation from parent node" from the default value no, to yes. After hours of google research, playing around with the site template (WSP) file, I still not able to come to a good solution.
I would like to automatically inherit the top navigation bar to a new created subsite. Creating a Site definition is not an option, because then I would have to start with my templates from scratch again.
I've read that I can modify this by changing the Onet.xml file, but which one shall I modify? the global Onet.xml , the site definition Onet.xml or the Onet.xml which is included in the site template wsp file?
