By default, a new top-level device group is inserted at the bottom of the list, denoting a lower ranking. Creating a sibling group allows you to insert a device group into a specific position in the list of device groups, defining different ranking for the new group. You can insert the new sibling group immediately above or below the selected upper-level group.

To create a top-level device group, complete the following:

1. Open the **Settings** icon > **Setup** > **Collection** **and** **Groups** > **Groups**.
2. Do one of the following:
  - To add a top-level device group, click **Add** in the bottom-right corner of the groups window.
  - To add a sibling group, right-click a top-level group and select **Add** > **Sibling Above** or **Sibling Below** from the shortcut menu.  
The **Add Device Group** dialog appears.
3. In the **Parent ID** field, NetMRI automatically sets the ID of the parent group. It is "0" for a top-level or sibling group.
4. Enter a **Name** for the new group. The group name is shown in all group-related displays and reports, so the group name should be meaningful without being too long.
5. Enter a **Membership** **Criteria** regular expression. For more information, see [*Understanding Device Group Membership Criteria*](https://infoblox-docs.atlassian.net/wiki/spaces/netmri754/pages/105944041).
6. For **Type**, select either **Basic** or **Extended**. By default, **Basic** is selected. For more information, see [*Creating Extended Device Groups*](https://infoblox-docs.atlassian.net/wiki/spaces/netmri754/pages/105943968).
7. Click **Save** **&** **Close** or **Save** **&** **New**.
