ComboBox Item:IsSelected

[antid2]

Wondering is there a way to tell if a combo box item is selected, i know you could do what the wiki says and output the name, but that's not what i'm wanting, see i've made a combo box for categories, when they click say...Cars or w/e...it shows only cars in the table, not drinks or food, so im wondering if it's possible to say

if ListCombo:GetSelectedItems()[1] then

but the problem is, when i click other choices, it's still showing everything, not that one table..

local ShopItems = vgui.Create( "DPanel", nInv ) 
ShopItems:SetPos( 125, 50 )
ShopItems:SetSize( nInv:GetWide() - 25, nInv:GetTall() - 25 )
ShopItems.Paint = function()
    if ListCombo:GetSelectedItems()[1] then
		for k,v in pairs(iScript.Items.Drinks) do
		local nItemB = vgui.Create("DPanel")
		nItemB:SetSize(60,60)
		nItemB.Paint = function()
			surface.SetDrawColor(Color(215,186,0,255))
			surface.DrawRect(0,0,nItemB:GetWide(),nItemB:GetTall())
		end
		
		local nItemB2 = vgui.Create("DPanel", nItemB)
		nItemB2:SetPos(5,5)
		nItemB2:SetSize(50,50)
		nItemB2.Paint = function()
			surface.SetDrawColor(Color(40,110,4,220))
			surface.DrawRect(0,0,nItemB2:GetWide(),nItemB2:GetTall())
		end
		
		local nIcon = vgui.Create("DModelPanel",nItemB2)
		nIcon:SetSize(50,50)
		nIcon:SetPos(0,0)
		nIcon:SetModel(v.Model)
		nIcon:SetCamPos( Vector( 0, 0, 30 ) )
		nIcon:SetLookAt( Vector( 0, 0, 30 ) )
		function nIcon:LayoutEntity( ent )
			ent:SetAngles( Angle( 90, 0, 0 ) );	
		end
		nIcon.DoClick = function(btn)
			SelModel = v.Model
			NameText = v.Name
			WeightText = v.Weight
			DesText = v.Desc
			Class = v.Class
			ButtonShow = true;
			UpdateModelData()
		end
		nInv:AddItem(nItemB)
	end
    end
end

This is urgent, thanks in advance
