Hi,

• When we group attributes, the +/- to fold/unfold the group of attributes doesn't work on the front page (webin_site). The attributes stays always unfolded.
• The +/- icons works in the Webin Admin interface

     6. Add a Text line attribute:
            * Select "Text line" in the attributes dropdown
            * Click on "Add attribute"
            * Fill in the form fields:
                  o Name: "Title"
                  o Identifier: "title"
                  o Category: "Default (content)"
     7. Add an XML Text attribute:
