Hi,
1. Your template override the Joomla original Register/Edit Page. The Tabs are generated by a javascript but works only on original Joomla template (or compatible): I fix this with rename folder from /templates/jm_consilium/html/com_users to /templates/jm_consilium/html/xcom_users

The next field is never shown on registration because the parent group was unpublished: I have publish now.

2.

Secondly, I can not really see how I can set it up so that when a user selects a value in a select field, there comes a data set and by choosing a different value should arise another dataset

Sorry but I not understand, can you explain me with an example?

3. Usergroups. Yes it's correct, the conditions add/remove groups, but registered group is assigned by Joomla, you can choose default usergroup from Administration->Users->User Manager->Options. So if I choose "Forfatter" on registration, I go on these groups: registered and forfatter

Last but not least, there are missing some documentation so you can get any easier going.

I agree with you. Unfortunately, we are very focused on the development of new features. Anyway in next release we will improve some tips.

Hi and thanks for your (fast) reply

Regaring field set , let me give an exampel:

In the first tab/screen the user can choose usertype A or B

If you are user type A the will be e.g this fields to fill out

Field 1
Field 2
Field 3
Field 4
Field 5

If you are user type B the will be e.g this fields to fill out

Field 1
Field 3
Field 6
Field 7

Hope this give som better understanding

Regards

Simply! you can use conditions to assign usergroup and to hide/show fields

Hi and thanks for your reply

Could you give me an example of how to set it up when a user signs up

Regards

No problem.

I have created these field (like your question in above post)
Usertype
Field 1
Field 2
Field 3
Field 4
Field 5
Field 6
Field 7

Usertype Field is a select with these options
1|Group 1
2|Group 2

I have set conditions on Usertype field (see screenshot)

Now if I select Group 1 on Usertype I have these fields
Field 1
Field 2
Field 3
Field 4
Field 5

if I select Group 2 on Usertype I have these fileds
Field 1
Field 3
Field 6
Field 7

Still the conditions assing Usergroup Group 1 or Group 2
