We've now got our columns in groups and can expand and collapse them.
In this video, we look at three features related to moving columns:
lockPositionproperty: locks columns to the first position in the grid
suppressMovableproperty: locks any movement of the column (it is still possible to move other columns around it)
marryChildrenproperty: columns of the group always stick together
In the next video, we'll learn about pinning columns.
