# Categories

While location types are used for styling locations on the map, **categories** are intended for **filtering** and **enhancing search experiences.** You can also assign locations to multiple categories if needed.

For more info, [read here](https://docs.mapsindoors.com/products/interface-overview#categories).

### Subcategories

Subcategories add an extra layer to your categories, allowing you to create even more **advanced filtering** and search options for your end users, making the search experience easier and more efficient.

* When you assign a category as a child or subcategory, you cannot use it as a parent.
* You cannot delete a parent category without first removing its children.
