You can change the order in which items are displayed in a region.
Notes:
When items in a region are sorted by title or size, you cannot
rearrange them. The Arrange Items icon, 
,
is not displayed in the region toolbar. To rearrange these items,
the page designer or a user with the appropriate privileges must edit
the region's properties and select "Default"
as the Sort By option.
You must be logged on as a page owner or as an authorized user with the appropriate page or item-level privileges.
Navigate to the page that includes the items you want to rearrange.
Note: If you do not see the page that you want to work with, you may not have the appropriate page access privileges. See your page group administrator to gain access.
Switch to Edit mode.
Note: Click Customize if you want to rearrange the items only on your own version of the page.
In the region that contains the items that you want to rearrange,
click .
In the Arrange Items list, select an item and use the arrows to reorder it in relation to the other items in the list. Repeat this step for other items you want to rearrange.
When you are done, click OK.
