Shortcode to list items NOT show buttons

I am using the classifieds plug in but the shortcodes supplied only seem to trigger buttons. What I would like is a shortcode that lists the items.

So I could have 3 tabs on 1 page. 1 tab displays Items "Offered". Another tab lists all the items "wanted". Another tab displays "My Ads". And then just a button to add a listing.

Otherwise I have a relatively empty page with buttons on them which looks a bit odd and not very user friendly.

Please does anyone know how to fix this?
