Select field -> conditional query

Hi again,

is it possible to have a conditional query like the following:

query:
   fetch: site.find('page').field.toStructure.filterBy("option", "{{ toggle1 }}")

when toggle1 = true

or how to realize that?
thx alot!

What is toggle1?

just an example for a toggle field.

try page.toggle.toBool()without the curly braces.

It works, but not live.
Page reload is needed to change the select options.

Any chance to dispatch an “get new options” event?
