You can, for example, organize page types in groups, to make it easier for editors to select the correct page type when creating pages in edit view. Properties can be grouped and ordered under tabs in the **All Properties** editing view.

## Content types

To group content types, add the `GroupName` property to the **content type** to specify a group, and use the `Order` property to determine the order in which the groups are displayed. This is used, for example, when creating pages in edit view and listing content types in the admin view.

**Example:** Two page types, **StandardPage** and **ArticlePage**, belonging to the groups **Basic pages** and **Facts articles** respectively, where the Basic pages group is displayed first because it has the lowest sort order.

```csharp
[ContentType(GroupName = "Basic pages",
  Order = 1,
  DisplayName = "StandardPage",
  GUID = "abad391c-5563-4069-b4db-1bd94f7a1eea",
  Description = "To be used for basic content pages.")]
public class StandardPage: PageData {}

[ContentType(GroupName = "Facts articles",
  Order = 2,
  DisplayName = "ArticlePage",
  GUID = "b8fe8485-587d-4880-b485-a52430ea55de",
  Description = "Basic page type for creating articles.")]
public class ArticlePage: PageData {}
```

The result when creating a page in edit view:

This can also be applied to other types of content, for example, products and variants in Optimizely Commerce.

## Properties

**Properties** can be grouped under [tabs](https://nuget.episerver.com/compare-database/). Use the `Display` attribute to specify the `GroupName` that is displayed as a tab. The `Order` property controls the order of the displayed properties on the tab.

**Example:** The Article page has two properties – `Author` and `Classification`, which are displayed under a tab named **Details**. The `Author` property is displayed first on the tab because it has the lowest sort order number.

```csharp
[Display(
  Name = "Author",
  Description = "Name of article author.",
  GroupName = "Details", Order = 1)]
public virtual String Author {
  get;
  set;
}

[Display(
  Name = "Classification",
  Description = "Genre or type of article.",
  GroupName = "Details", Order = 2)]
public virtual String Classification {
  get;
  set;
}
```

The result when editing an article in the **All Properties** editing view:

### Built-in groups

Optimizely Content Management System (CMS) provides a set of built-in tabs/groups used by built-in properties. These built-in groups are **only used for properties**, not for content types. You can add your custom properties to the groups, to make them display under the built-in tabs. Constants for the built-in tabs are defined in `EPiServer.DataAbstraction.SystemTabNames`.

| Name         | Sort index | Description                                                                                                                                             |
| ------------ | ---------- | ------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `Content`    | 10         | Default group used for properties that does not specify a group name. **Note:** The actual group name is `Information`.                                 |
| `Settings`   | 30         | Used for some of the more advanced built-in properties. **Note:** The actual group name is `Advanced`.                                                  |
| `PageHeader` | N/A        | The page header that is shown above the tabs or by scrolling up in the **On-Page** editing view. The actual group name is `EPiServerCMS_SettingsPanel`. |

The **Content** and  **Settings**tabs are available by default. Tabs can be edited from the CMS admin view. From here, you can also define access levels, to create tabs with properties only available for selected editor groups.

**Note**
Tabs without properties will not be displayed in the All properties editing view. Scheduling, Shortcut, and Categories are obsoleted groups.

## Group definitions

You can define sort order on individual content types and properties as described. The order set indirectly defines in which order *content groups* are displayed when creating content, and in which order *tabs* are shown when editing content in the **All Properties** editing view.

When the number of content types and properties increases, it is convenient to define the order of groups at a higher level, and then use order to sort among the content types and properties in each group. Normally you define groups as a list of **constants** that you use in the `DisplayAttribute`.

**Example:** The `ArticlePage` type with a `News` content type group, and a **Contact** tab with an `Image` property.

```csharp
[ContentType(GroupName = GroupNames.News, Order = 1)]
public class ArticlePage: PageData {
  [Display(GroupName = GroupNames.Contact)]
  public virtual ContentReference Image {
    get;
    set;
  }
}

public static class GroupNames {
  public
  const string News = "News";
  public
  const string Contact = "Contact";
}
```

You can also define the group names as constants in a separate class, and decorate the class with the `GroupDefinitions` attribute (which is automatically picked up). You can define multiple classes with the `GroupDefinitions` attribute, but you can only define a single group name on one class. Groups defined in code cannot be edited in the admin view.

Set the order in which groups are displayed with the `Display` attribute. Properties and content types are sorted within each group by each order. Groups that have no order defined get `Order=-1` and are displayed first.

## Apply access levels

When you group content types and properties, you can apply access levels so that an editor must be part of a role, function, or other criteria to access the group. The required access level applies to groups of properties and groups of content types.

**Example:** The Contact group with access level set to **Publish**.

```csharp
[GroupDefinitions]
public static class GroupNames {
  [Display(GroupName = "MyNews", Order = 1)]
  public
  const string News = "News";
  [RequiredAccess(AccessLevel.Publish)]
  public
  const string Contact = "Contact";
}
```

## Override sort order of built-in groups

Groups without defined order fall back to the indirect sorting and have the sort index set to -1. You can override built-in groups to change sort order.

**Example:** Override the default sort order for the **Content** tab.

```csharp
[GroupDefinitions]
public static class GroupNames {
  [Display(Order = 1000)]
  public
  const string Content = SystemTabNames.Content;
}
```

You cannot edit groups that are defined in code from the admin view.
