Layout Templates allow you to choose how portlets will be arranged on a page. They are simple table or CSS-based containers into which portlets can be dropped and sit within the body of the page. Liferay Portal comes with several built-in layout templates, but if you require 4-1-4 column layout you may wish to use this custom layout template. A thumbnail is displayed when the end user clicks "Edit Link" from the Dock bar.

This layout will appear in your Page Layouts once installed.
