F2 menu???

trying to make an F2 menu for my gamemode. looked on wiki and it said to use:
and then input your VGUI, and it will automatically link to f2. absolutely nothing happens!

Can someone crap me out a F2 menu to stick in CL_init? or anywhere else if need be? doesnt even need a VGUI, just an accurate Line to tell thet it IS IN FACT going to pop up when we hit F2

Have some code. Also, the wiki is a great resource, learn to use it…
– Display the team menu
function GM:ShowTeam(pl)

Stick that in init.lua and have the function to open the menu included client side.
