Bottom

The bottom section of the template design (from Quickstart) was built using two rows (top, bottom and bottom) and 6 module positions together.

Footer

In the footer, we used two modules published on the footer1 and footer2 module positions.

The footer area with the copyright note can be edited from the template settings. You can find the settings from Joomla Dashboard > Extensions > Site Template Styles > shaper_languageschool - Default > Template Options > Basics > Footer. 

And footer menu is based on the Menu module published on the "footer2" module position. 

The Footer is a core template feature, and it inherits all the functionalities from the Helix Ultimate framework. You can make the customizations in your way by understanding the framework better. You can head over to Helix Ultimate Documentation for further reference.
