Help screen column header Display Select
From Joomla! Documentation
- Display #. (Use Global/Hide/Show) Whether to hide or show the Display # control that allows the user to select the number of items to show in the list. An example is shown below.
If there are more items than this number, you can use the page navigation buttons (Start, Prev, Next, End, and page numbers) to navigate between pages. Note that if you have a large number of items, it may be helpful to use the Filter options, located above the column headings, to limit which items display.
