How to hide/delete links on navigation bar?

I had a look around to find answers but the threads were all about buttons and stuff.

I want to remove gallery, calendar, groups and faq (I´d add this to my rules topic).
I thought I´d be able to make them visible only for admins but the options are greyed out.

I have an invision forum, if it makes a difference.

Sorry, is it possible to delete/hide them all, cause I found the topic where it says how to create a control panel for members in a widget.
I want to keep the widget now and delete the links in navigation bar (Home­, Profile, Messages, ­Search, Gallery, Memberlist, Faq­, Calendar, Usergroups, Posts since last log in, own posts and unanswered posts). Maybe just leave log out button.

Question: Why in the world would you do this? You are making your members do nothing.

Calendar & Gallery just go to admin panel >> Modules Tab >> Calendar Management >> Activate >> Save

Gallery Management >> Activate >> No >> Save

Place this in your CSS

Admin Panel >> Display Tab >> Colors >> CSS Sheet

I'll give you some of the code to place but just look at the url of the page and take anything after the www.help.forumotion.com/groupcp.forum <= Remove the groupcp.forum


Place it in the [href="/PLACE THE URL HERE"]

You take away home and you can't move around the forum so you look at one page

Faq

Code:

a[href="/faq.htm"] {display: none;}

Members list

Code:

a[href="/faq.htm"] {display: none;}

Groups

Code:

a[href="/groupcp.forum"] {display: none;}

Code that you will use to place in the CSS

Code:

a[href="/groupcp.forum"] {display: none;}

Thanks. I just don´t want them to be up there. I´ll put them on the side into the widget. I´ll leave them on the forum, but just in a different place.
If there´s a better way to make the forum look nicer I´m open for suggestions.
