Listing Entries Display
On the Sections Archive page, you can choose whether to display Entry Titles only, or the entire Entry by selecting your preference in the drop-down menu.
On the Sections Archive page, you can choose to display all of the Entries under a certain Section rather than paginating your Entries. Checking this box will also enable a 2 column layout so that pages with many Entries will be easier to find Entries on.
To display all of them, check the box and remember to click Save Changes.
