To
add a region to a page, you must have at least one of the following privileges:A region is an area on a page that displays information and can contain either portlets, items, or tabs. When you first create a page, it consists of at least a single region. After creating a page, you can edit it to add more regions.
To
add a region to a page, 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
If you have Full Customization privileges on a page, you can add regions to your own tabs when you customize the page; you cannot add regions anywhere else in the page.
Go to the page with which you want to work.
Switch to Edit mode.
In the page toolbar at the top of the page, click Layout.
Use

and 
to add a region (region 1) to the page. For example, say your page
currently has a single region:
Click
in region 1 to create a second region (region 2) of the same width
directly below region 1:
Click
in region 1 to create third region (region 3) to the right of region 1:
Note: Region 3 is the same height as region 1 (the region next to which it was added), not the height of the entire page.
When you edit a page and add a region, the type of the region is undefined (i.e., it has the potential to contain either portlets or items), regardless of the type of the region where you clicked the add region icon (the source region). You can then change the region type to designate the region as either a portlet or item region. When you do this, the new region will use the same property settings as the source region. If you change the new region to be the same region type as the source region, the new region will use the same attribute list as the source region. Otherwise, the new region uses the default attribute list for that region type.
When you customize a page and add a region, the type of the region is the same as the source region.
If the page is based on a page template, the region configuration is determined by the page template, therefore you will not be able to add more regions directly to the page. To add more regions, you need to add those regions to the page template (if you have the appropriate privileges).
