  Hi there,

  Initially, I found the dropdown menu very challenging while trying pure javascript.

  Because .querySelector only chooses the very first element with the same class name, I could only control the first dropdown menu by id.

  Then I turned to use jQuery, I use $(this) to control which menu should be dropdown.

  Still, I'd like to know how to achieve this feature with only JS. 🥲🥲

  use querySelectorAll to select all the element with the same class name then loop through each of them to add the event listener for the dropdown. better still utilize the idea of event delegation
