import wixData from ‘wix-data’;

export function dropdown2_change(event, $W) {
villagefilter ();
}

async function villagefilter() {
// retrieve all items from the Category dropdown
const categories = ( await $w(“#dataset2”).getItems(0, 20)).items

// get ID of currently selected Category
const selectedCategoryId = categories[$w(“#dropdown2”).selectedIndex]._id

$w(‘#dataset3’).setFilter(
wixData.filter().eq(“dest”, selectedCategoryId)
)
}
