title: How to trigger the HTML Select onClick event (activates select dropdown with options)
body: <p>I want to know how to trigger the <code>onClick</code> event of any <code>select</code>(html combobox element).</p>
  
  <p>I tried to do <code>$('#MySelect').click();</code> using <code>jQuery</code> and tried <code>document.getElementById('MySelect').click();</code> using pure javascript.</p>
  
  <p>But the two don't fire the dropdown event that have the options of the select.</p>
  
  <p>Ps: i have sure that selector <code>$('#MySelect')</code> exists.</p>
