I would like to know how I can change the default value for the detail region with a group by setup.

<div class="row-fluid">
  <div class="span6">
    <div data-binding-id="repeat1" data-binding-repeat="{{mitarbeiter.data.groupBy( &quot;name_pos&quot; )}}">
      [h5]{{$name}}[/h5][list]
        <div data-binding-id="repeat2" data-binding-repeat="{{$value}}">
          <li onClick="dmxDataBindingsAction('selectCurrent','repeat2',this)"><a href="#">{{VORNAME}} {{NAME}}</a>[/*]
        </div>[/list]
    </div>
  </div>
  <div class="span6" id="mitarbeiter_det" data-binding-detail="repeat2" data-binding-id="mitarbeiter_det">[img]" alt="" class="aligncenter" data-binding-src="../../../assets/bilder_ma/{{BILD}}" />
    <h5 class="tighten-height">{{VORNAME}} {{NAME}}[/h5]
  </div>
</div>

At the moment I get the first value of repeat2 in the last group of repeat1. I would like to have the first value of repeat2 in the first group of repeat1 as default (mitarbeiter.data[0]).

How can I do this?

I hope you understand the problem I have. Any idea?

Hello Marcel,
Using such a layout this is not possible. This happens because the repeat region "repeat2" exists multiple times, it is nested in the "repeat1". So it overwrites the previous repeat regions and the first record from the last "repeat" region is shown in the detail.

Hello Teodor,
I understand the problem, but shouldn't it be possible to use mitarbeiter.data[0] as default?
Is there a solution with show/hide?
Could I show a region with mitarbeiter.data.[0] as default and hide the default region on load?

You can create 2 detail regions:

<div data-binding-id="detail2" data-binding-detail="repeat2">
{{mitarbeiter.data.[0].VORNAME}} {{mitarbeiter.data.[0].NAME}}
</div>

And

<div data-binding-id="detail1" data-binding-detail="repeat2">
{{VORNAME}} {{NAME}}
</div>

The first one will always show the first record, and the second one will show the selected record. You can add display:none to the second one so it is hidden by default.
Then on click behavior you can hide the first and show the second.

That is what I was looking for. Thanks a lot.
I found out that the detail region for the first record does not need the data-binding-detail="repeat2"

Hello Teodor,
I have an additional question on this topic.
The problem now is, that on the first click on a name you can see the default image of the last repeat for <1s before the correct image is shown. It seems to flicker.

Any idea how to solve this?
