Thank you for your quick answer Peter. About the first case, can you think of any alternative solution? Here’s an image of how it looks like:
As you can see, the group has a lot of fields, and there are many more that aren’t shown. The best solution would be that it behaves as a normal row and not show it’s fields as a long string but as columns, but I guess I can’t do something like that. Can you think of any alternative solution? I would really apreciate that.
About the second case, thanks for the suggestion, it was very helpful.
By the way, is there any page where I can see which are all the parameters that may recibe the function properties such as groupsrenderer?
