select not working correctly

Navigation
2

I'm facing a problem, of which I did not find tutorials clear enough on the internet so I could learn how to solve it, which apparently seems simple but I can not solve it. The problem is to get <select> down when you click it. However, when I click on 1, all 3 go down:

As in the code below, I tried to change the class to drop1,drop2 . I also changed in .css and .js, but I'm sure I did something wrong, just do not know where.

Style.css: 

body {
  background: #35414a;
}

.drop {
  width: 20em;
  margin: 5em auto;
  font-family: pfs-bold;
  color: #86919a;
  text-transform: uppercase;
  position: relative;
  -webkit-transition: width 0.5s;
  transition: width 0.5s;
  will-change: width;
}
.drop .option {
  padding: 1em;
  cursor: pointer;
  background-color: #333333;
}
.drop .option:not(.active) {
  display: none;

You can open each menu by taking the index of what has been clicked, but leave all menus with class drop same (and not drop1 , drop 2 ...): 

 mIdx = $(this).closest('.drop').index('.drop');

I have also changed the references of .drop by creating a single variable $drop for the whole function, besides sending this variable to the function triggerAnimation() that will do the menu animation.

See it working: 

$(document).ready(function() {
  $(".drop .option").click(function() {
    mIdx = $(this).closest('.drop').index('.drop');
    var val = $(this).attr("data-value"),
    $drop = $(".drop:eq("+mIdx+")"),
    prevActive = $drop.find(".option.active").attr("data-value"),
    options = $drop.find(".option").length;
    $drop.find(".option.active").addClass("mini-hack");
    $drop.toggleClass("visible");
    $drop.removeClass("withBG");
    $(this).css("top");
    $drop.toggleClass("opacity");
    $(".mini-hack").removeClass("mini-hack");
    if ($drop.hasClass("visible")) {
      setTimeout(function() {
        $drop.addClass("withBG");
      }, 400 + options*100); 
    }
    triggerAnimation($drop);
    if (val !== "placeholder" || prevActive === "placeholder") {
      $drop.find(".option").removeClass("active");
      $(this).addClass("active");
    };
  });

  function triggerAnimation($drop) {
    var finalWidth = $drop.hasClass("visible") ? 22 : 20;
    $drop.css("width", "24em");
    setTimeout(function() {
      $drop.css("width", finalWidth + "em");
    }, 400);
  }
});
