Hi @ma77hiaz, welcome to our forum! I have edited the title of your question to follow our guidelines.
I guess the headings themselves should have no numbering, I mean not only in the outline but also in the main text? For this you can make the headings by writing
#heading(numbering:none, level: 1)[My Heading]
or if you prefer to use the markup syntax (=
) for making the heading: you can do it in a #[...]
scope with different settings than other headings:
#[
#set heading(numbering: none)
= My Heading
]
