Hi all,
i have two question:
i add sematic ui labels to html and they appear and suddenly disappear, then if I change page on my app the re-appear and i don t know why. Example here: http://eelst.cs.unibo.it:8092
second: how can i add menu behaviour properly? how to organize semantic, jquery and other extra script loading in my page?

Thanks in advance
