When you create a horizontal line, DataView locks the item at the specified row position. Any existing item entry is displayed in the center of the row.
Thus you create a non-selectable item. It is used to logically separate selectable items in a menu and forms some kind of »heading« for a group of items. This can help the user to orientate espacially in longer menus.

dal_men_dra_lin idm,5,1,5,0
Vertical line for column display at 10th column as long as the menu length:
dal_men_dra_lin idm,1,10,0,10
