Hi Luis,
Greetings from Syncfusion.
As mentioned in our
documentation, you can add the multiple sections into the document. When you add more than one section into the word document, the section starts from the next page by default.
You can also add a new section that starts on a same page(continuous) by specifying the BreakCode as NoBreak(for continuous section).
Regards,
