Example on adding more chains

In qb-core/shared/items.lua add this
['']  					= {['name'] = '', 			['label'] = '',		['weight'] = 1,  		['type'] = 'item',  	['image'] = 'chain.png',  			['unique'] = true,  	['useable'] = true,  	['shouldClose'] = true,  	['combinable'] = nil, 	['description'] = ''},


in qb-chains/client.lua add this
RegisterNetEvent('chains:client:*event_name_here*', function(itemName)
    if not wearing then
        TriggerEvent('animations:client:EmoteCommandStart', {"adjusttie"})
        QBCore.Functions.Progressbar("chain_misc", "Putting on chain..", 3000, false, true, {
        
            disableMovement = false,
            disableCarMovement = false,
            disableMouse = false,
            disableCombat = true,
        }, {}, {}, {}, function() -- Done
            SetPedComponentVariation(ped, 7, 10, GetPedTextureVariation(ped, 7), 15) --- 7 is for neck accessories(teef) the 10 is for number chain and 15 is for number texture
            wearing = true
            
            TriggerEvent('animations:client:EmoteCommandStart', {"c"})
        end)
    else
        TriggerEvent('animations:client:EmoteCommandStart', {"adjusttie"})

            TriggerEvent('animations:client:EmoteCommandStart', {"c"})
        end)
    end
end)


in qb-chains/server.lua add this
QBCore.Functions.CreateUseableItem("*item_name_here*", function(source, item)
