DModelPanel not showing bodygroups!

Hi! in the DModelPanel it doesnt show bodygroups? is there a way around this?

my code:

local playermodel = vgui.Create( "DModelPanel", Frame )
playermodel:SetSize( ScreenScale( 200 ), ScreenScale( 210 ) )
playermodel:SetModel( ply:GetModel() )

playermodel.Entity:SetBodyGroup( id, num )

thanks! but how would i get it to show the bodygroup the player has?

You can learn from the default player editor:
