# 2.2 Configure enumerations

You'll learn how to configure enumerations that we will later use as parts of component fields

**Lesson 2.2 - References & Enumerations: Configure enumerations:**

In this lesson you'll learn how to configure enumerations that we will later use as parts of component fields.

## Overview

When we create product entries for our e-commerce, we want to be able to select values - such as product size or color - from a dropdown menu. This makes sense for our project because we want to be able to only publish products in certain colors & sizes. Making this a dropdown in our content creation screen ensures that only the values we predefine will be used for those product characteristics.

In Hygraph, you do this by adding a dropdown menu to your model. This dropdown gets the list of values from an enumeration that you need to configure before you create the dropdown field.

An enumeration is a predefined set of values that represents a list of possible options. We can use enumerations to group values within a type and then use them when we add a dropdown field.

We will be using enumerations for the components that we are going to create in our next lesson. Let's configure them.

## Configure enumerations

Adding enumerations is very simple.

![Adding enumerations](https://hygraph.com/images/classic-docs/getting-started/add-enumeration-screen.png)

We always add them in the same way:

1. In the Schema editor, we click on `+Add` next to `Enumerations`.
2. We then type in a `Display name`, which is the name that we will see in the Schema.
3. We also add an `API ID`, which we can use later to access the enumeration through the API Playground.
4. Next, we add enumeration values by typing them in the `Values` field and then clicking on `+Add to list`. We will need to do this for each value.
5. To save our enumeration, we simply click `Add enumeration`.

For this tutorial, we will add 4 enumerations: separate sizes for shoes and clothes, and separate colors for wearables and decor.

Use the following information to add them:

**Clothes size**

|Field              |Input                                            |
|-------------------|-------------------------------------------------|
|Display name       |Clothes size                                     |
|API ID             |ClothesSize                                      |
|Enumeration values |One by one, add the following: XS, S, M, L, XL   |

**Shoes size**

|Field              |Input                                                                                                                      |

|Display name       |Shoes size                                                                                                                 |
|API ID             |ShoesSize                                                                                                                  |
|Enumeration values |One by one, add the following: Size_35, Size_36, Size_37, Size_38, Size_39, Size_40, Size_41, Size_42, Size_43, Size_44    |

After adding your **Enumerations** the left sidebar should look like this:
