Hello,

thanks for the reply.
Could you provide an example please?

I can undestand that with this renderer function I can filter groups based on the index=-1 value. But how can I determine when the group doesnt have any items and should not be shown when filtering?

Thank You in advance

Hello,

thank you for your reply but the issue is with categories (groups)

http://jsfiddle.net/91qcr7g6/

open the dropdown.. search for lets say “c3” You will see that ‘A’ and ‘B’ categories still shows up

Thank You
