The Friends module comes with the following web parts. All of them are located in the Community -> Friends web part category. This page brings just a brief overview of them. For a detailed description of each web part's properties please see Kentico CMS Web parts reference.
Friends viewer
This web part can typically be used on user's profile page for viewing their friends. If you right-click the user's avatar image, you will be offered several tasks, as you can see in the screenshot below.
The following web parts are actually on-site equivalents of the friends management administration interface described in the Friends management topic:
Friends list
This web part displays a list of all friends of the current user.
Friends waiting for approval
This web part displays a list of all users waiting for the current user's friendship approval.
Rejected friends
This web part displays a list of all users whose friendship the current user rejected. These users can't request the current user's friendship while they are in this list.
My pending requests
This web part displays a list of all users whose friendship the current user requested.
Request friendship
This web part displays only a link that, when clicked, opens the Add a new friend dialog.
My friends
This web part combines the five previously mentioned web parts in one single web part. It's functionality is fully equal to the UI in CMS Desk -> My Desk -> My friends.
