Web part inheritance allows you to create specialized web parts based on other web parts. Inherited web parts use the same [code files](https://docs.kentico.com/13/custom-development/extending-the-administration-interface/developing-web-parts/creating-new-web-parts.md) as the original, but you can:

- Change the definitions of the [web part properties](https://docs.kentico.com/13/custom-development/extending-the-administration-interface/developing-web-parts/working-with-web-part-properties.md)
- Prepare [custom layouts](https://docs.kentico.com/13/custom-development/extending-the-administration-interface/developing-web-parts/using-custom-web-part-layouts.md)

To create an inherited web part:

1. Open the **Administration interface** application and switch to the **Web parts** tab.
2. Select the category where you want to place the web part.
3. Click **New web part**.
4. Select **Inherit from an existing** as the **Web part** option.
5. Type a **Display name** for the inherited web part.
6. Choose the parent web part through the **Inherit from** selector.
7. Click **Save**.

Inherited web parts work like regular standalone web parts. The main difference is that inherited web parts have the **Inherited from** field showing the parent web part instead of the _File name_ selector that specifies the source file.

Modify the properties of inherited web parts on the **Properties** tab.

> **Info:** You can:
>
> - Set the **Default value** for properties
> - Determine whether properties are visible in the web part configuration dialog (**Display field in the editing form**)
> - Modify the appearance and behavior of properties
> - Add additional properties
>
> You cannot:
>
> - Remove inherited properties
> - Change the **Field name**, **Data type** or **Size** of inherited properties

> **Tip:** **Tip**: Click **Reset field** to revert all settings of a modified property back to the original state (the system copies the property settings from the parent web part).

When you add new instances of the web part to a template, the system pre-configures the properties according to the specified values.
