Using pdb-single

I am using Participants Database to hold short biographical records.

I have created a page that just contains all my records. Clicking on the selectable field The name of the individual takes you to the detail page for that record. Now the setup Guide” says:

On the “Manage Database Fields” page you can determine which fields get shown in the list and which column they will be in. This is under the “Display” column and you give each field you want to show a number which determines which column the field will appear in. Zero means it won’t show at all.

Now I cannot find this in the settings at all. Where exactly is it?

On my detail page, I have just [pdb_single] which initially was not very clever as it listed all the fields for all the Field Groups, so I deleted the inbuilt field groups I was not using. That has partially fixed the problem but it still displays all the fielda but some I want to hide like the ID and my Sort field.

Can the layout of [pdb_single] be edited?

Can [pdb_list] be edited to?
