Switching between 1 and 2 column layout in Typst

[Bosmeneer]

Hi quarto developers,

I've been trying to learn Quarto, Typst and LateX for some time now. I have a feeling that these tools can really help me achieve my goal, but I end up with dead-ends either way I go.

My goal
Create PDF reports for customers based on some external metadata. E.g, customer A should retrieve chapter A, B, C, while customer B should receive chapter X, Y, Z. The content within those chapters can also vary.

When diving into LateX I get frustrated with the language itself, it feels messy, slow and not easy to learn.
I've been looking into Typst and it is much easier to read, and error handling is way better, however I am running in to a specific challange:

My page layout should be sometimes 1-column, sometimes 2-columns. It depends on the chapter content. I cannot figure out whether this is possible in Typst. I'd like to avoid any use of .lua files and would like to stick to an extension with a -show.typst and -template.typ file

Can anyone help met out?

Many thanks!
