Can you describe more about what you are trying to achieve?
If you want to add fields to the related list
Navigate to the Page Layout that you wish to add fields to a Related List for. You can access the Page Layout via the Setup menu or the Edit Layout on the object itself.
Once you are on the edit screen of the Page Layout, navigate to the Related List that you wish to adjust the number of fields for. Select the wrench icon beside the Related List and add your fields
You can fire a relationship query which will give you all the detail(related list records) records for each of the master record and use VF page to create a section to display the records. You have to then add the results of the query to a text field, unsure how this can be done
Query looks like this
List<Master__c> ListOFMasterRecords = new list<Master__c>([select id (select id from Detail__r)from Master__c]);
