Okay. Not sure how to push the values directly to the dropdown. The only way I can think of is to create an array and push the values from tierss to it with a loop. Then use the newArray options for the dropdown. Hope this helps. If not, then hope someone else can provide a better answer. Good luck.
$w.onReady(function () {
let newArray = [];
for (var i = 0; i < tierrs.length; i++) {
newArray.push(
{"label": "" + tierrs[l], "value": l.toString()}
);
}
$w("#dropTier").options = newArray;
})
