Decimal chapter numbering in Libreoffice

Question

I am trying to number my chapters in Libreoffice decimally. The best way to illustrate what I mean is by an example:

1 Chapter One
1.1 Chapter One Sub One
1.2 Chapter One Sub Two
1.2.1 Chapter One Sub Two Sub One
1.2.2 Chapter One Sub Two Sub Two
1.3 Chapter One Sub Three
2 Chapter Two
2.1 Chapter Two Sub One
2.2 Chapter Two Sub Two

How would I do this automatically in Libreoffice?

Answer 1

In LibreOffice Writer, select in the main menu Format, Bullets and Numbering... and in the Bullets and Numbering dialog, select the Outline tab. Pick the outline style you prefer.
