I’m using jqGrid v4.6.0 and I need to change the text that is displayed when using grouping. For example I’m grouping by a case number and I also want to display the case description in the group. I tried two different approaches:

1) Using a custom formatter on the group field (following the next example that oleg kindly provided)

2) Using formatDisplayField according to the following example:

Everything works as expected (I can add some text for example), but if I set hideFirstGroupCol: true the format function is no longer called.

What can I do to get the desired behaviour?

Thanks in advance!
