dear forum,

in my blueprint i am trying to fetch the children of a specific page for my select.  
the parent page of these children should be dynamic so my idea was to put a select field in the site.yaml and then use this value in my query:

site.yml:

```auto
containerpage:
  label: Containerpage
  type: select
  options: query
  query: site.children

```

mypage.yml:

```auto
relatedpage:
  label: Related Page
  type: select
  options: query
  query: site.find( {{ site.containerpage }} ).children

```

however this does not work. i managed to get the functionality i want via a siteMethod in a plugin, however that kinda felt like shooting cannons at sparrows so i am curious if there is in fact a smoother way to do it?🙂

Try

```auto
query: site.find(site.containerpage.toPage()).children

```

You need to create a page object from the select field value. Why don’t you use a pages field instead of the select?
