When writing transformations for displaying [Users](https://docs.kentico.com/k12sp/managing-users.md) or [Groups](https://docs.kentico.com/k12sp/community-features/groups.md), you can enclose the transformation into a container control that provides a context menu triggered by right-clicking a user or group.
> **Note:** **Note**: You can only add controls into transformations of the **ASCX** type. The system does not render context menu controls in the other transformation types.
## Writing transformations for user context menus
To add the context menu to lists of users, enclose your transformation inside the **cms:usermenucontainer** control ([edit the transformation](https://docs.kentico.com/k12sp/developing-websites/loading-and-displaying-data-on-websites/writing-transformations/creating-transformations-for-pages.md#editing-transformations) used by the component that displays the list of users):
```html
```
## Writing transformations for group context menus
To add the context menu to lists of groups, you need to enclose your transformation inside the **cms:groupmenucontainer** control ([edit the transformation](https://docs.kentico.com/k12sp/developing-websites/loading-and-displaying-data-on-websites/writing-transformations/creating-transformations-for-pages.md#editing-transformations) used by the component that displays the list of groups):
```html
```
## Modifying the context menu design
The default controls used for context menus are stored in **\CMSAdminControls\ContextMenus**:
- **GroupContextMenu.ascx**
- **UserContextMenu.ascx**
These two controls are used automatically for the Group or User context menus. If you want to modify the design of the context menus, edit the controls in Visual Studio.
You can also develop custom context menu controls. In this case, you need to add the **MenuControlPath** parameter to the _cms:usermenucontainer_ or _cms:groupmenucontainer_ controls in the transformation and set its value to the path to your control:
```html
```
