You can specify whether tabs appear on the left or right side of a region.
The following example shows the same region with different tab alignment settings:
To
change the alignment of tabs in a region, you must have at least one
of the following privileges:
Manage All privileges on the page group to which the page belongs
Manage privileges on the page
Manage global privileges on All Pages
Go to the page with which you want to work.
Switch to Edit mode.
Click 
in the region that contains the tabs for which you want to change the alignment.
Notes:
You can only change the tab alignment in a region that already contains at least one tab.
Make sure you click the icon in the tabbed region itself (that is, the icon to the right of the tabs), not in a region within the tab.
In the Tab Alignment list, choose whether the tabs are displayed on the left or right side of the region.
Click OK to return to the page.
