Use preference centers in Optimizely Data Platform (ODP) to gather user information to personalize your campaigns and increase customer engagement.

## Update customer fields

The preference center window displays default elements, such as an **Image**, a **Header**, a **Text Box**, a **Checkbox**, and a **Submit Button**. You can customize this further by including additional fields to capture user information. 

1. Go to **Settings > Preference Centers**.
2. Click an existing preference center or [create one](docId\:JORRWPVj2LAwnVYZc9MPg). 
3. Go to **Elements > Forms**.
4. Drag and drop a **Text Box** on the main design page. 
5. Click the **Text Box** and access the **Details** tab.  
6. Select **First Name** from the **Field** drop-down list.
7. Click **Save**.

Do not make these fields *required* because users must be able to update their subscription preferences without supplying information.
