Help needed with expanding nested references in a Sanity query

3 replies
Last updated: Jul 20, 2021
Maybe I'm losing my mind, or don't have enough caffeine in my system, but I can't work out how to expand a nested reference, but also keep its sibling. I have a 
submenuItems
array that can contain URL or a reference to another document. However, I can't seem to expand any references it encounters without losing the sibling submenuItem that happens to be a normal url/link.

Sample, full query result:

*[_type == "navigation" && id == "kevin-navigation"]{
  links[]{ 
    name, 
    href, 
    submenuItems[]->{ 
      ...
    }
  }
}
This expands the references entirely, but loses the sibling items of a different 
_type
whilst if I remove the 
->
it returns the opposite. Something to do with the projection, and mapping over I think, but can't work it out 😂 Any help mucho appreciado.

I think I may sussed it, thanks for Anders code snippet. Just in case anyone is stuck in a rut and questioning their career-choice for a few hours 😄
