ComboBox LEGACY

If you need to set some attributes or listen to events on native input , you can put it inside with Textfield directive as shown below

If you receive your id to text mapping from the server, you would need to recreate items and stringify when new data comes, so they will be observables and you would need async pipe in the template

Note that virtual scroll can imperatively remove focused option from DOM. This causes ExpressionChange errors and to solve those take a look at a tiny IndexChange directive included in this example.
