# 6.4.3.2. Managing the content of the hierarchy
{% hint style="info" %}
Registry Administrators can add and/or remove Geo-Object Types or groups to the hierarchies for the organization they are a part of.
{% endhint %}
{% hint style="info" %}
Geo-Object Types or groups from organizations you are not a member of can also be added to a hierarchy from your organization.
{% endhint %}
To add a Geo-Object Type (group) to a hierarchy:
1. Go to the *Geo-Objects and Hierarchies* module either by clicking the Geo-Objects and Hierarchies module icon in the main menu page or by clicking the hamburger menu () in the upper right corner and selecting *Geo-Objects and Hierarchies*.\\
2. If needed, expand the *Hierarchies* column on the sidebar by clicking the arrow at the end.\\
3. Scroll down the *Hierarchies* column to the organization you are a part of. Click the name of the hierarchy you want to add a Geo-Object Type (group) to to select it (the box of the selected hierarchy will change to a different color). This will display the area to add Geo-Object Type (group) as part of the hierarchy to the right of the *Geo-Object Types* and *Hierarchies* columns (represented by the rectangle with dotted lines).\\
4. Find one of the Geo-Object Types (groups) that you want to add to the hierarchy in the *Geo-Object Types* column. If needed, expand the *Geo-Object Types* column in the sidebar by clicking the arrow at the end.\\
5. Click and hold on the name of the Geo-Object Type (group) and drag it to the area to add it to the selected hierarchy.
6. The display area will now show the Geo-Object Type (group) you have added to the hierarchy.
7. To add another Geo-Object Type (group), click and hold on the name of the Geo-Object Type (group) and drag it on top of the Geo-Object Type that is already part of the hierarchy.
8. You will then have the option to choose whether to add this new Geo-Object Type (group) as a parent (above) or child (below) of the Geo-Object Type already in the hierarchy. Drag the Geo-Object Type (group) to the chosen place in the hierarchy (parent or child) until the selected place turns blue and drop it there.
9. Once added, you will see the new Geo-Object Type (group) connected to the other Geo-Object Type (group) in the hierarchy (either above or below the other Geo-Object Type (group), depending on the relationship you chose). In the example below, the *Health Post* Geo-Object Type was added as a child of the *Health Center* Geo-Object Type in the *Health Facility Reporting Hierarchy*.\\
10. Repeat steps 4 to 7 to add other Geo-Object Types (groups) to complete the hierarchy.
{% hint style="danger" %}
Important notes:
1. Two different Geo-Object Type groups cannot be added together in a linear hierarchy.
2. A Geo-Object Type group can be only a child and never a parent to a Geo-Object Type in a hierarchy.
3. A Geo-Object Type can have more than one child in a hierarchy.
{% endhint %}
To remove Geo-Object Types (groups) from a hierarchy:
1. Go to the *Geo-Objects and Hierarchies* module either by clicking the Geo-Objects and Hierarchies module icon in the main menu page or by clicking the hamburger menu () in the upper right corner and selecting *Geo-Objects and Hierarchies*.\\
2. If needed, expand the *Hierarchies* column in the sidebar by clicking the arrow at the end.\\
3. Scroll down the *Hierarchies* column to the organization you are a part of. Click the name of the hierarchy you want to remove a Geo-Object Type (group) from to select it (the box of the selected hierarchy will change to a different color). This will display the Geo-Object Types (groups) that are part of the selected hierarchy.\\
4. Find the Geo-Object Type (group) you want to remove from the hierarchy and click the gear icon () at the end of its name.\\
5. From the options that appear, click on **Remove from hierarchy**.\\
6. A message window will appear confirming if you would like to remove the Geo-Object Type (group) from the selected hierarchy, click the **Submit** button.\\
