Detailed Description

Represents a filter group with multiple string options.

They are passed to the server as a single form parameter separated by a delimiter. The parameter name is the group name. E.g. groupname=opt1;opt2 .

If all options are selected they are replaced by the term "all".

There is also a single DB query modification for the whole group.
