# Is inventory open

> Checks if an inventory is currently open.

Checks if an inventory is currently open. If no inventory ID is provided, returns whether the inventory UI is currently active (any inventory open). If an inventory ID is provided, checks if that specific inventory is open.

<CodeGroup>
  ```lua Export theme={null}
  exports['jaksam_inventory']:isInventoryOpen(inventoryId)
  ```

  ```lua Example theme={null}
  -- Check if any inventory UI is open
  local isAnyInventoryOpen = exports['jaksam_inventory']:isInventoryOpen()

  if isAnyInventoryOpen then
      print('An inventory is currently open')
  else
      print('No inventory is open')
  end

  -- Check if a specific inventory is open
  local isPoliceStashOpen = exports['jaksam_inventory']:isInventoryOpen('police_stash_1')

  if isPoliceStashOpen then
      print('Police stash is currently open')
  end

  -- Prevent opening another UI if inventory is already open
  if not exports['jaksam_inventory']:isInventoryOpen() then
      -- Open custom UI
      TriggerEvent('myScript:openCustomUI')
  else
      notify("Can't do it while inventory is open")
  end
  ```
</CodeGroup>
