How can I do that using nested repeaters? I have a category and a sub-category. But sub-category count is not stable. It depens on it's category. It can be any number 1 to 20.

Answer 1

This article seems to achieve the very same thing.

Instead of querying an XML file, you can query a DB or any dataset you like.

Answer 2

You can do that with code-behind - add to each repeater HiddenField and put the id within. on prerender, foreach repeater - set the correct select command.
