$w.onReady(function () {
   $w('Checkbox').onChange((event) => {
   let elementID = event.target.id
   
   deactivate_allCheckboxes()
   .then(()=>{
      $w('#'+elementID).checked = true;
   })
});

function deactivate_allCheckboxes() {
   $w('#checkbox2).checked = false;
   $w('#checkbox3').checked = false;
   $w('#checkbox4').checked = false;
   $w('#checkbox4').checked = false;
}

Of course you can LOOP the “deactivate_allCheckboxes”-function and improve this code.

It is just an quick and simple example.
