Sections and columns can be merged in two different ways.
Go to Lessons.
If you titled your page something other than Lessons, select the title of the page as it appears in your Tool Menu.
Note: The Lesson page must already contain content and one or more section breaks before you can combine sections.
Method 1: Select 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). Selecting the Merge button will merge the selected content block with the block above it.
Method 2: Select Reorder.
Select Reorder from the Actions Menu.
Select the merge arrows.
Select the merge arrows to delete the column/section break.
Select Save.
View merged columns/sections.
The two sections or columns will be merged to be one big block with borders around them. All items will be displayed in order vertically inside the content block borders.
