LibreOffice 7.5 Help
Specifies the number of columns and the column layout for the section.
Sections follow the text flow behavior of the page they are inserted into.
For example, if you insert a section that uses a two-column layout into a page style that uses a four-column layout, the two-column layout is nested inside one of the four columns.
You can also nest sections, that is, you can insert a section into another section.
