Select Filter: Show values in sorted order?

I want to show the values in select filter in sorted order. How to do that?

Couldn’t you clarify your issue.
Here is the working example: … _srnd.html

You can see that the options in the select_filter are sorted alphabetically.

If you are loading list of values by connector, you can define custom options connector for the column and use render_sql with ORDER BY instruction to force the necessary order.
