How to compact list items horizontally?

Questions
1 
+ Main Level
    + Sublist 
    + Sublist
    + Sublist

Expected output

  1. Main Level
    a. Sublist b.Sublist c.Sublist

I am already using:

#let henum(it) = [
  #let items = if it.func() == enum {
    enum.children.len()
  } else if it.has("children") {
    it.children.filter(x => x.func() == enum.item).len()
  } else {
    panic("Unknown input")
  }
  #show enum.item: it => [#it #colbreak()]
  #columns(items)[
    #it
  ]
]

this is still writing lots of repeating code. I want to taget level 2 list like

#show: enum.items.where(level:2): henum

Currently, you can’t target enum at specific levels, see Add level field to bullet list items for easier format and style minipulation · Issue #4520 · typst/typst · GitHub

The comments in the github issue discussion give a workaround, which I combined with the code example you linked:

#let henum(it) = [
  #if it.has("children") and it.children.len() == 1 {
    return it
  }
  #let items = if it.has("children") {
    it.children.filter(x => x.func() == enum.item).len()
  } else {
    panic("Unknown input")
  }
  #show enum.item: it => [#it #colbreak()]
  #columns(items)[
    #it.children.enumerate().map(((idx, child)) => {
      // ensure consistent numbering if not manually numering items
      if child.number == none {
        let fields = child.fields()
        let num = fields.remove("number")
        let body = fields.remove("body")
        return enum.item(
          ..fields,
          idx + 1,
          body
        )
      }
      child
    }).join()
  ]
]


#let depth = state("depth", 0)

#show enum.item: i => {
  depth.update(d => d + 1)
  i
  depth.update(d => d - 1)
}
#show enum: l => {
  context if depth.get() == 2 {
    henum(l)
  }
  else {
    l
  }
}
