Hi Dark Beccio,
In your specific case I will suggest to use our ComboBox component and I have prepared a little code snippet on how to achieve the functionality you intend to.
//In your Js file :

window.onload = function () {
    const comboBox = document.querySelector('smart-combo-box');
    comboBox.dataSource = [
        { "label": "Afghanistan", "value": "AF" },
        { "label": "land Islands", "value": "AX" },
        { "label": "Albania", "value": "AL" },
        { "label": "Algeria", "value": "DZ" },
        { "label": "American Samoa", "value": "AS" },
        { "label": "AndorrA", "value": "AD" },
        { "label": "Angola", "value": "AO" },
        { "label": "Anguilla", "value": "AI" },
        { "label": "Antarctica", "value": "AQ" },
        { "label": "Antigua and Barbuda", "value": "AG" },
        { "label": "Argentina", "value": "AR" },
        { "label": "Armenia", "value": "AM" },
        { "label": "Aruba", "value": "AW" },
        { "label": "Australia", "value": "AU" },
        { "label": "Austria", "value": "AT" },
        { "label": "Yemen", "value": "YE" },
        { "label": "Zambia", "value": "ZM" },
        { "label": "Zimbabwe", "value": "ZW" }
    ];
    setInterval(function(){
        console.log('Value',comboBox.selectedValues)
    },300)
};

//In you HTML file:
<smart-combo-box auto-complete="manual" min-length="1" selection-mode="zeroOrOne"></smart-combo-box>
One thing to have in mind although that these are different components they share similar functionality.
Please, do not hesitate to contact us if you have any additional questions.
