Forums / Cotonti / Support / List, extrafields, filtering

Good day.

I have a need to make a filter using list.
For axample:
we have a list like http://www.cotonti.com/downloads/plugins/users-communites/
and i want to view sublist with author=Trustmaster

In Seditio ther was something like

list.php?c=cat&s=date&w=desc&o=extra1&p=test

In result I can see list of articles from category=cat where extrafield=extra1 and this extrafield contain "test" value

How can I Make the same in COTONTI ?

PS sorry for my poor English
