Can someone please elaborate more on this topic. I have tried to override the content/edit/ezmatrix.tpl but it doesn't seem to take. Which template is used by the attribute_edit_gui function when a matrix data object is edited?
1. Create an override for the edit_attribute-template
2. Insert a switch in it, matching on the label of the field you wan't to manipulate. Leave the original template content in the standard case-block
3. Copy the standard template content into the case-block matching your field
4. Change the layout of it, for example by adding/changig CSS-class of the element, or adding a div with a class around it. This gives you the oppurtunity to manipulate the apperance of the field without even touching the template again 5. Update your CSS to correspond with the template
Thank you very much. I managed to override this template and add the case for my specific node. All that worked just like you suggested. I'm still experimenting with the css part. It is not yet clear to me what css is active for the attribute_edit_gui function.
