[help] access the current field

[its-dibo]

fields = [{
 key: "example",
 type: "select",
 props:{
  options: data$.pipe(
   //<------- access "field" here
    tap(res=>{ field.required = res.lengh>0 })
 )
}
}]

other solutions
I tried other solutions, but all of them are not elegant

• access the field after creating the object

fields = [{ ... }]
fields[0].props.options = data$.pipe(
 tap(res=>{ fields[0].required = res.length>0 })
)

• use init hook: this makes the code got more complicated, all logic of all props are existing in one function
• use expressions: I want to set the initial state only, not watch for each chnges
• use initializer function; not supported by formly

fields=[
 ...
  options: (field, model) => data$.pipe( ... )
]
