Sections and columns can be merged in two different ways.
Go to Lessons.
Click on the Lessons tool in the Tool Menu to display the page.
Note: The Lesson page must already contain content and one or more section breaks before you can combine sections.
Method 1: Click the Merge button.
The Merge button looks like two arrows pointing in toward each other. It is located in the top left corner of each content block (either section or column).
Clicking on the Merge button will merge the selected content block with the block above it.
