How to implement an input, when clicked, a drop-down list would appear with a choice of operator.
I found this solution using database:
<input name="city" list="cities" /> <datalist id="cities"> <option value="Naples" /> <option value="London" /> <option value="Berlin" /> <option value="New York" /> <option value="Frattamaggiore" /> </datalist> But this method is more suitable for autocomplete, and I need to just be able to select the operator code and he signed up for input. Can anyone have a ready-made solution or some kind of library?
