I am missing collapsible groups with the group widget.

Like you will find in form 2 on this page:

Jesper, as far as I can see the only difference from normal groups is an icon before the label. You can insert an icon using wiki syntax. For example you can insert a checkbox using {checked}. Use Ctrl+Space for a list of available icons. Let me know how this works for you.

Hi Peter,

Thanks - you are so right. It works for me.
