Redmine

Hello,

I want to remove the possibilities to go on Gantt lable, wiki, forum, ... I want to keep only the label : Activity and ticket.

I can easily remove these label IF I'M INSIDE A SPECIFIC PROJECT,

but if I'm on the main page PROJECT, i can't find where I can remove these lable to access the page.

I attach a picture to show which label I want to remove ..
best regards
