Whats the max number of participants that will get displayed on a topic?

The 6th participant was annoymous which disappeared when a member post. I am wondering if I can increase this number and if this is expected behavior.

Is this on a PM in the header or this?

If it’s the 1st, I believe the logic is here:

github.com/discourse/discourse

frontend/discourse/app/components/header/topic/info.gjs

main


      
          get maxExtraItems() {
            return this.args.topicInfo.tags?.length > 0 ? 5 : 10;
          }

github.com/discourse/discourse

frontend/discourse/app/components/header/topic/info.gjs

main


      
          get participants() {
            const participants = [
              ...this.args.topicInfo.details.allowed_users,
              ...this.args.topicInfo.details.allowed_groups,
            ];
            return participants.slice(0, this.maxExtraItems);
          }

this is just in the topic list , I gave up on customizing the header participants. These replies are part of Discourse with no modification.

This list is about the topic’s featured users. I’m not sure if you can modify it. Perhaps you could, programmatically.
