Thunderbird Contacts CardDAV doesn't support groups/lists #9226

Description

@mrtumnus

Nextcloud server version: 24.0.6
Nextcloud Contacts version: 4.2.2
Thunderbird version: 102.3.3
OS: Windows 10 Enterprise 21H2 19044.2130

On the documentation page for Thunderbird sync (/user_manual/groupware/sync_thunderbird.rst), the "recommended" method is to use native Thunderbird support for CardDAV contact integration. However, this method does not support contact groups. The option is greyed out:

The only way I have found to accomplish this is by using a plugin like Cardbook.

I wonder why the native method is recommended? At the very least, we should add a note indicating Contact groups are not supported (which, to me, is a significant limitation).

    Sorry, I know this is not discussion thread, but can anyone find some information on WHEN thunderbird plans on rolling out this enhancement? Shouldn't be a question of "if".

    Still present. In user_manual/groupware/sync_thunderbird.rst, the native Thunderbird CardDAV section (lines 13-27) has no mention that contact groups/lists are not supported. The CardBook add-on section (line 43) is labeled as an 'alternative' without explaining why you'd choose it.

    A note in the native Contacts section should say that contact groups are not supported by Thunderbird's built-in CardDAV and that CardBook should be used if group sync is needed.
