Good afternoon Sergio, I could not understand 100% what you are trying to do, but an idea would be to use a button for the user to click if he does not find your option, which would show an input field, follow an example:
HTML
<select name="something" id="">
<option value="a">a</option>
<option value="b">b</option>
</select>
<button>Não achei a opção</button>
<input type="text" placeholder="Digite aqui" />
CSS
input {
display: none;
}
Javascript
$('button').click(function() {
$('select').fadeOut();
$('input').fadeIn();
});
And here in case you want to see it live: http://codepen.io/leofontes/pen/RoGeOr
I hope I’ve helped, it’s an option, surely there are numerous possible ideas.
The tag itself select does not have this option, you have to emulate something similar, using input and consequently, after insertion of text, open a div below with the search result. It would look something like this component of Angular Material ??.
