Helix3 is the best and the most advanced Joomla Template Framework packed with mind blowing features. About one of this features we have info below and in this post :https://www.joomshaper.com/blog/a-detailed-guide-to-the-helix3-layout-manager
Layout Manager allowing you to build flexible and beautiful layout based on module positions. Layout Builder is one of the unique features of Helix3 which allows anyone to customize the existing template in any shape without having any programming language! In the layout builder we used 6 columns. Those 6 columns covered the whole width of our layout. If you want to create 4 columns then have to use wider blocks for every column.
Using Layout Manager is easy to master, learn. Following icons legend should help you understand which icons are responsible for what feature/setting. We suggest to make a copy of current layout to keep it for later in case if you would delete all rows and you forget how they were placed at the beginning.
Each layout which you create can be saved and used later for example in template copy.
Note! Do not forget to save column settings on popup window - save button is at the bottom, also general template must be saved after changes.
