All selection in drop down

I wonder if anyone knows how to add an “all” selection in wix dropdown??

I know there’s a few codes out there in the forum but I do not know where to add it for it to function!

I’d be very grateful for a bit of help on this !! thanks.

Here is my code:

import wixData from 'wix-data';
 
export function searchclick(event) {
    search();

    $w("#repeater1").show();

}
 
function search() {
 
    wixData.query("PropertiesCyprus")
        .contains("country", String($w("#dropdown1").value))
        .and(wixData.query("PropertiesCyprus").contains("cities", String($w("#dropdown2").value)))
 
        .find()
        .then(results => {
            $w("#repeater1").data = results.items;

        });
 
}

$w.onReady(function () {

});

export function dropdown1_change_1(event, $w) {

$w("#button33").show();

locationCityFilter();
}

function locationCityFilter (){

$w("#dropdown2").enable();

$w("#dataset4").setFilter( wixData.filter()

.eq("country", $w("#dropdown1").value)

);

}

Hi. I don’t see where you assign the options to the dropdown in your code.
