To add a new list, click on Data Lists. Next, click on Lists.
Enter a Name for your list and select a Parent Location for your list to appear under.
Attach the list below Parent's Content (the data list will only be visible when the parent is a normal article and it's content has not been disabled) or attach the list below Parent's Summary (the data list will only be visible when the parent is linked to it's parent via summary).
Choose how many Columns you would like the list to have and then choose how many Entries to display on one page. Next, select which Fields (List) you want to show. This determines what entry information is to be shown - the name is always shown. To add more fields, see instructions here.
Next, choose what Fields (Entry) you would like displayed. This determines what entry information is to be shown on the entry details page. To enable this, be sure to check the Link to Entry Details Page checkbox. If this is the same as the Fields (Listing) column, check the box Same as Fields in List.
If you wish to add search capabilities to your list, check the Enable search capabilities for this list box at the bottom of the page. Choose whether or not to Show only the search form (initially) by checking the box.
