# Customize a screen

To customize a screen on NotionApps, follow the steps below:

1. Open the app builder and select the screen that you want to customize from the app preview (in the center of the app builder).
2. The configuration section for the screen is visible on the right side of the app builder.

{% hint style="info" %}
A screen can have customizations based on the type of screen. For example, list screens like View Items or Update Items have customizations for filtering, sorting, or in-app filtering items. Screens like View Single Item allow for customizations by adding different components to represent the item/page, such as text, images, or buttons.
{% endhint %}

3. In the configuration section, you can configure various options such as the layout of the screen, the visibility of fields, the display of images, and more.

{% hint style="success" %}
As you make changes, they will reflect in the mobile preview in the center of the app builder. These changes are *automatically saved* but only show up on your link after publishing the app.
{% endhint %}

Over the next pages, we will talk about specific customizations for these screens.
