Layouts in AdapTable include which columns should be Row Grouped.
Additionally you can specify / store information about which Row Groups are open - so that they will re-open when the Grid next loads.
This requires 2 steps:
- Set includeExpandedRowGroups to true in Layout Options
- Add a list of Column Values in the ExpandedRowGroupValues property of the Layout object in Layout State
In this demo we have set up our Predined Config so that AdapTable is grouped on the 'Ship Country' column with the 'Belgium' and 'Denmark' groups expanded.
