Drop down revert back to original options

Hi all,
I have a dropdown I am using to function as a search. I have it set up to show values, and when one is chosen it works beautifully. However I cannot get it to revert back to the original options once an option has been chosen. Please can you offer some advise? Code below:
import wixData from ‘wix-data’;
$w.onReady( function () {
wixData.query(“Reviews”)
.limit(100)
.find()
.then(results => {
const uniquecompanyToReview = getUniquecompanyToReview(results.items);
$w(“#companyreviewdropdown”).value = undefined;
$w(“#companyreviewdropdown”).options = buildOptions(uniquecompanyToReview);
});
function getUniquecompanyToReview(items) {
const companyToReviewOnly = items.map(item => item.companyToReview);
return [… new Set(companyToReviewOnly)];
}
function buildOptions(uniqueList) {
return uniqueList.map(curr => {
return {label:curr, value:curr};
});
}
});
export function companyreviewdropdown_change(event) {
let SearchValue = $w(“#companyreviewdropdown”).value;
$w(“#reviewdataset”).setFilter(wixData.filter().contains(‘companyToReview’, SearchValue)
);
}

Try adding a reset button on the page.

There is a good example from Vorbly here.

Otherwise, simply search the forum itself for reset button and you will get many old posts back…
