import wixData from 'wix-data';

$w.onReady(function () {
    $w("#checkboxCollection").onChange(() => {filterView();});
    $w("#checkboxRoom").onChange( (event, $w) => {filterView();});
});
 
 function filterView(){
 let collection = $w("#checkboxCollection").value
 let room = $w("#checkboxRoom").value

    console.log('collection', collection);
    console.log('room', room);
 
    $w("#dataset1").setFilter( wixData.filter()
        .hasSome("collection", collection)
        .hasSome("room", room)
    )

    .then( () => {let count = $w("#dataset1").getTotalCount();})
    .catch( (err) => {
    console.log(err);
    } );
 }

Now you have an example :grin:
