Like controllers, Stimulus actions are defined using a data attribute in the markup: you add the attribute to the DOM element whose events you want to watch. In our case, we want to add a button that says “Hide”—the new button goes right after the title element that displays “Favorite Controllers”:

 <div class=​"text-3xl font-bold"​>
  Favorite Concerts
  <button
  class=​"​​<%=​ SimpleForm.​button_class​ ​%>​​ py-1 text-xl font-semibold"
  data-action=​"click->favorite-toggle#toggle"​>
  Hide
  </button>
 </div>
