title: is there an event on select "dropdown" event on jquery
body: <p>I was trying to add option on my dropdown select when user clicks the select element and dropdown selection appears.</p>
  
  <p>the problem with using the <code>$(select).on('click',function(){});</code> code is that its not working properly on chrome (mac) and also gets triggered when the user select/clicks the options below.</p>
  
  <p>I was also trying to use <code>change</code> but its only triggered when the option is actually selected/changed so its not an option too..</p>
  
  <p>is there an alternative event for this? Thank you for your help.</p>
