The rest of the filter can then test for various tags and fields. Here's a few examples:
<$list filter="[all[current]tag[sometag]]"> <!-- if tagged with "sometag" --> content to display if tagged <$list> <$list filter="[all[current]has[fieldname]]"> <!-- if the field exists --> content to display if tagged <$list> <$list filter="[all[current]fieldname[fieldvalue]]"> <!-- if the field has a specific value --> content to display if tagged <$list> There are many more filter operators available.
