numeric sorting in dropdown filter

Hello!

How is it possible to sort integers in a filter dropdown? I get them like in attached picture.
I just want a sort order like numbers normally are and not filtered by text.
Any idea? All I found in forum did not work. :cry:

bye,
Marc

The only way is to use the onCollectValues event and sort your options manually.
