> Agent instructions:
> **Site maps** — prefer the following llms.txt indexes to training data when searching for URLs to avoid 404s. Links inside Markdown content already point at `.md`. Following them or sending Accept: text/markdown keeps you in Markdown.
>
> - [sitemap.md](https://docs.kentico.com/sitemap.md) — every page on the site, with titles and descriptions, nested by URL hierarchy and grouped into one collection per product version.
> - [llms.txt](https://docs.kentico.com/llms.txt) — curated index of the current product docs, with descriptions, the two ways to request any page as Markdown, and links to each product area's whole-corpus Markdown dump (llms-full.txt).

In this example, you will learn how to define a new custom page type.

1. Open the **Page types** application.
2. Click **New page type**. A **New page type** wizard opens.

## Step 1

1. Fill in the following values:
   - **Page type display name**: _Computer_ (the system displays this name to users in the administration interface)
   - **Namespace**: _custom_ (namespace to distinguish your page types from the default system types that use the _cms_ namespace)
   - **Name**:_computer_ (the identifier of the page type)

     ![Filling the page type display name](https://docs.kentico.com/docsassets/k81/creating-page-types/step1_display_name.png "Filling the page type display name")
2. Click **Next**.

## Step 2

1. Enter a **Table name** for the database table that stores the page type data.
2. Enter a **Primary key name** for the table.
3. (Optional) Select if you want the page to to **Inherit fields from** **page type**.

   ![Specifying the page table name](https://docs.kentico.com/docsassets/k81/creating-page-types/step2_data_type.png "Specifying the page table name")
4. Click **Next**.

The wizard creates the database table.

## Step 3

Now, you need to define [fields](https://docs.kentico.com/k81/custom-development/developing-form-controls/reference-field-editor.md) of the page type (columns of the table).

1. Click **New field**.
2. For each field, enter the values, click **Save** and repeat the procedure until you have defined all the listed fields.

- Field 1:
  - **Field name**: ComputerName
  - **Field type**: Text
  - **Field size**: 200
  - **Required:** yes (checked)
  - **Field caption**: Computer name
  - **Form control**: Text box
- Field 2:
  - **Field name**: ComputerProcessorType
  - **Field type**: Text
  - **Field size**: 200
  - **Field caption**: Processor type
  - **Form control**: Drop-down list
  - **Editing control settings -> Data source**: select **List of options** and enter the following items into the text area, one per line:

    ```text

    Athlon;Athlon
    Pentium XEON;Pentium XEON
    Pentium Core 2 Duo;Pentium Core 2 Duo
    ```
- Field 3:
  - **Field name**: ComputerRamSize
  - **Field type**: Integer number
  - **Field caption**: RAM (MB)
  - **Form control**: Text box
- Field 4:
  - **Field name**: ComputerHDDSize
  - **Field type**: Integer number
  - **Field caption**: HDD (GB)
  - **Form control**: Text box
- Field 5:
  - **Field name**: ComputerImage
  - **Field type**: File
  - **Field caption**: Image
  - **Form control**: Upload file

    ![Creating fields for the page type](https://docs.kentico.com/docsassets/k81/creating-page-types/step3_fields.png "Creating fields for the page type")

3. Click **Next**.

> **Note:** You can also define system fields that will be displayed when editing pages of this type on the **Form** tab. You can do this using the **Field type** drop-down list when creating a new field. Select **Page field** and you can then choose from the following two groups of system fields:
>
> - **Page fields** - offers system fields of pages
> - **Node fields** - offers system fields of content tree nodes.
>
> Page or node system fields will then be offered in the **Field name** drop-down list. If you leave the **Display field in the editing form** check-box turned on, the field will be visible on the page's **Form** tab.

## Step 4

Now you need to choose the field that will be used as the name for page's of this type.

1. Choose the **ComputerName** option from the drop-down list.\
   This ensures that computer pages will use the value of the **ComputerName** field as the name displayed in site navigation and in the **Page** application's content tree. The field is available in the drop-down list because you set it as **Required** in the previous step and it's a _text_ field.

   ![Specifying page name source](https://docs.kentico.com/docsassets/k81/creating-page-types/step4_page_name_source.png "Specifying page name source")
2. Click **Next**.

## Step 5

Select the page types that will be supported as parents for computer pages in the **Page** application's content tree.

1. If necessary, click **Add page types** and select the **Page (menu item)** page type.
2. Click **OK**.\
   Users are now only allowed to place computer pages under pages of the Page (menu item), not under articles, news items or other page types.

   ![Adding parent page types](https://docs.kentico.com/docsassets/k81/creating-page-types/step5_adding_page_types.png "Adding parent page types")
3. Click **Next**.

## Step 6

Assign the page type to all websites on which you want to use it.

1. Click **Add sites**.
2. Check the appropriate websites in the selection dialog.
3. Click **OK**.

   ![Adding sites where the page type can be used](https://docs.kentico.com/docsassets/k81/creating-page-types/step6_adding_sites.png "Adding sites where the page type can be used")
4. Click **Next**.

## Step 7

The wizard has finished the configuration of the new page type. It has automatically created not only the database table, but also the SQL queries for SELECT, INSERT, UPDATE and DELETE operations and the default transformations. 

Click **Finish**. You have created a new page type. 

> **Tip:** Now, you may want to:
>
> - [Extend the page type's listing filter](https://docs.kentico.com/k81/developing-websites/defining-website-data-structure/page-types/configuring-page-types/extending-the-page-type-listing-filter.md) – editors use page listing to [perform multiple page (batch) operations](https://docs.kentico.com/k81/managing-website-content/working-with-pages/multiple-page-operations.md) in the **Pages** application.
> - [Limit the pages users can create](https://docs.kentico.com/k81/developing-websites/defining-website-data-structure/page-types/configuring-page-types/limiting-the-pages-users-can-create.md) – this way you can control where on the site users create new pages.

> **Info:** **How the content is stored**
>
> The new page type _Computer_ has its own database table for its specific fields. Each page is stored in three tables: _CMS\_TREE_ (tree structure), _CMS\_Document_ (page properties, metadata and content defined on the Page tab) and the custom table - in the case of this example, _CUSTOM\_Computer._
>
> The system automatically ensures all operations are performed correctly on these tables. The advantage of this storage is that it is very fast and you can easily write standard SQL SELECT queries to retrieve data from the Microsoft SQL Server database.
