Why is the selected attribute not firing?

Question

Angular

Please help me understand why the selected attribute does not always work in select fields. My form has 3 such fields, but the selected attribute worked in only one of them. Live demo here.

Answer 1

You are setting the initial value incorrectly. We cut it out, and in the createSubForm [selected]method, instead of an array of all possible values, we pass one to the FormControl constructor. Like so .
