[SOLVED] Show Joomla usergroups in frontend profile

Id'd like to show (not edit) the Joomla usergroups of every user in its profile in the frontend
How can I achieve this?

We don't provide a field for that. You'd need to use CB Query Field to query for that information or create a Custom HTML field and substitute in the information. Example substitution as follows.

[cb:if usergroup includes "2"]I have Registered Usergroup[/cb:if]

Great. But it does more than I want :

Ex. : I put in the Custom HTML Description
[cb:if usergroup includes "29"]Premium[/cb:if] [cb:if usergroup includes "13"]Member[/cb:if] [cb:if usergroup includes "2"]Registered[/cb:if]

The Registered, Member and Premium groups are hierarchically dependent.
For the sake of simplicity, in our site, a user is Registered OR Member OR Premium exclusively.
This is the information I expect : the name of the group to which she really belongs to.

In fact, the instruction you gave me rebuilds the hierarchy. Therefore I get:
Registered
Member Registered
Premium Member Registered

How can I simply get
Registered
Member
Premium

On way would be to have "else" : could you provide the syntax?
Another way, if it exists, to have a function that gives only the real group.

There is no "else" feature in substitutions at this time. You could do the below.

[cb:if usergroup includes "29"]Premium[/cb:if]
[cb:if usergroup includes "13" and usergroup !includes "2"]Member[/cb:if]
[cb:if usergroup includes "2" and usergroup !includes "13"]Registered[/cb:if]

That might work by excluding the group above it.

Well.No. It gives the same.
The problem is not at the input level, but at the output of the function " includes ".
This function, as far as I understand, gives all the parent groups of a group.
I understand that this may be useful for some purpose, but not in my case.

Don't spend too much on this, we will use it as it is.

Thank you for your attention

Usergroups work off inheritance so yes the usergroup condition is checking against the current and inherited usergroups. You can try the below for exact usergroup matching.

[cb:if gids includes "29"]Premium[/cb:if]
[cb:if gids includes "13"]Member[/cb:if]
[cb:if gids includes "2"]Registered[/cb:if]
