I'm needing help with filtering repeaters.

This is the code I’m using:

I have a dropdown box for users to select a location. This is working fine. But I would like to add a filter to only show Artist from the category field that I have in my database.
At the moment the repeater is pulling all of the categories from my category filed. I don’t want to add another dropdown menu. Is there a way to add a filter or condition into the code?
Many thanks for any help on this.

import wixData from ‘wix-data’;
$w.onReady(() => {
$w(“#dataset4”).setFilter(wixData.filter().eq(‘location’,));
});
export function location_change(event) {
let myValue = $w(‘#location1’).value;
console.log(myValue,“myvalue”)
$w(“#dataset4”).setFilter(wixData.filter().eq(‘location’, myValue));

See the Wix API for repeater too.

As for additional queries, then just see the code examples in the Wix API reference for Wix Data Query.

Plus the same for additional filters in your setFilter.
