Loving the new datagrid, thanks for all the hard work! It appears that although you can make a custom column filterable, the filter does not actually work. In my case, the custom column contains a Select element (dropdown).
I have the exact same issue. The filtering based on original database values work but filtering based on custom values does not. How can I make it work?
Can you try including each custom column’s database key in your column config, the same way you would for a regular column? The datagrid should pick it up automatically. If that doesn’t work, please show us what kind of filtering you are doing, Lukas, thanks!
