“Topic Format” functionality in Pages 4.x?

[opentype]

In IP.Content I could decide for each database field, if and how it would appear in forum topics, if it got posted there. 
How is that done in Pages? In the field settings I see nothing to set this up anymore. 

And when I look at the template which is probably used, there is just a foreach loop for “topicFields”. But where are those fields defined?

{{foreach $record->topicFields() as $id => $field}}
{$field|raw}
{{endforeach}}
<br>
<p><a href="{$record->url()}">{lang="content_view_record" sprintf="$record::database()->recordWord( 1 )"}</a></p>

Ensure topic posting is enabled for the database - the form field will *not* appear if topic posting is not enabled for the database.

It is available when editing any field in that database, on the first tab, under the 'Settings' heading, so long as that condition is met.

Thanks! That clears up what is happening. 
The specific database has forum posting turned off at the database level, but turned on for certain categories. Then the settings can’t be accessed even though it is used.
