})

please tell me where to add, thanks in advance

It is not clear what you are trying to achieve.

How do look like your related DATABASE-STRUCTURE?

What does mean…

…I need to see all options…
…???

What about something like that …

import wixData from 'wix-data';
let selection1, selection2, selection3;

$w.onReady(function () {    
    $w('#dropdown1').onChange(()=> {selection1=$w('#dropdown1').value, check();})
    $w('#dropdown2').onChange(()=> {selection2=$w('#dropdown2').value, check();})
    $w('#dropdown3').onChange(()=> {selection3=$w('#dropdown3').value, check();})
});

function check() {let filter = wixData.filter();
    if (selection1) {filter=filter.hasSome("subtitle", selection1);}
    if (selection2) {filter=filter.hasSome("subtitle", selection2);}
    if (selection3) {filter=filter.hasSome("subtitle", selection3);}
    $w('#dataset1').setFilter(filter);
}

Not tested → just some theoretical thoughts.

Now i think i understand what you are searching for.

You simply need a RESET-FILTER-OPTION right?

$w("#myDataset").setFilter( wixData.filter());

yes reset option please where do i put this is my code?

Try this one…

import wixData from 'wix-data';
 
$w.onReady(function() {
    $w("#myDataset").onReady(()=>{
        $w("myResetButtonIDhere").onClick(()=>{
            $w("#myDataset").setFilter(wixData.filter());
        });
    });
});
