Hi.
Can you add a bUnit test please, to check that the custom render fragments gets rendered and the

 <MudAvatar Class="@MaxAvatarClassname" Color="@MaxColor" Size="@MaxSize" Variant="@MaxVariant" Rounded="@MaxRounded" Square="@MaxSquare" Elevation="@MaxElevation">
                @($"+{_avatars.Count - Max}")
</MudAvatar>

doesn't.

@henon thoughts?

Hi, before merging I noticed that it would be better to name the template MaxAvatarsTemplate with an extra s. Could you rename it, then it can be merged.

You mean MaxAvatarsTemplateS? Are you sure about this one? In our codebase we use everywhere XYZTemplate.

[henon]

No I mean MaxAvatarsTemplate not MaxAvatarTemplate as it is now
