Options to display alternating background colors for collection view rows.
If there are more rows with content than there are visible rows, you will not see a difference between
the All option and the ContentOnly option.
| None | Do not alternate background colors for rows. |
| ContentOnly | Alternate background colors only for rows that have content. The background color does not alternate for empty lines. |
| All | Alternate background colors for all rows, regardless of whether they have content. The background color continues to alternate for empty lines. |
