I am new in Wordpress and what I really can't find how to do is the following: I have a new Page created from the CMS. This pages have different modules with text. Take for example this template http://www.templatemonster.com/demo/40000.html
There are three modules in the row with an icon, a heading and text. And below other four. How is possible so user be able to edit from wordpress each one of these modules separately?
