Panel: import sibling subpage in a select field

i am currently trying to make a import childrens of a sibling page.

The page is a one pager with a snippet structure similar to this

  • ā€¦
  • Slider
  • Exhibits
    • Exhibit A
    • Exhibit B
    • Exhibit C
  • Programs
    • Program A
    • Program B
  • Event
    • Event A
    • Event B
    • Event C
  • Other page
  • Yet another page

My goal is to import Sibling Subpages in a Slider. Here i want to have a structure with a select field. The Select field has all the subpages from the siblings. Is this possible?

Not using the predefined options. Solution: Use dynamic options via the JSON query API or the Controlled List plugin
