"No results" when repeater is empty

you can create an updateRepeater function and call it after the filter function wherever you’re using it.

function updateRepeater(){
 if($w('#repeater').data.length ===0){
       if(!$w('#no_results_title').isVisible){
         w('#no_results_title').show() 
       }
 }
 else{  
      if($w('#no_results_title').isVisible){
        w('#no_results_title').hide()   
      }        
 }
}
