**Item ID**
* Each item must have a unique value, as duplicating item IDs within the same menu can lead to errors.
* When connecting data from the web page to the app for visibility, use the item ID to search for the specific item.
* Please note that only English letters, numbers, and the special character (\_) are allowed for usage in item IDs.
