# Items Items are the most important constituent of any menu and it probably needs no introduction. As you might have got some references in the Categories section, these are the ones grouped under different categories and are the ones ordered and consumed by the end customers. In our system, an item is a standalone constituent, even if there are customizations attached to it. {% embed url="" %} Item Section in a menu {% endembed %} In UrbanPiper, you can have different items associated with different stores. If we take the previous example of Pizzas, in one store, there can be 30 pizzas that are sold but in another store of the same brand, only 28 might be sold. The category will hold all the 30 items but this association can be altered by associating or disassociating an item from the store. The same concept is extended to aggregator's platforms as well. You can have a certain set of items sold in one store for one aggregator and a different set of items sold in the same store for another aggregator. Items can be categorised into two types - items with no customizations and items with customizations. The latter can again be subdivided on the basis of the customizations (variants or add ons) which we will look at in the upcoming sections. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
