It is quite easy to add as many static content sections you want at the homepage. Simply create the page, setup your content, and add the related widget to the homepage structure.
Yeap. The page you are looking at is completely widgetized. Each section is controlled by a widget at the widgets area of the theme. You can easily edit them and re-arrange their order with simple drag and drop gestures. This offers the high flexibility that you need for your homepage’s layout.
There is an inbuilt shortcode generator for you also, with the most common elements like toggles, columns, buttons, etc. Enjoy browsing through Cluster and let us know if you have any questions! Thanks for stopping by!
