We've pulled down the latest build (2016.1.112) and looking to push it into our solution already using kendo.
We've noticed on the latest build frozen columns + grouping works differently:
Current build: If I group by a field and then collapse the group it only does this for the frozen columns rather than all.
Previous build ie .2015.3.930 : If I group by a filed then collapse the group it collapses everything (What we want/expect).
Is there a setting a setting to force the group close to close both the frozen and unfrozen columns?
