Animated Tags Input Based On Multi Select Box

In this tutorial, we will be making a jQuery script that converts the regular multi select box into an animated tags input field.

When you select options in the dropdown box, these options will be displayed in the input field in the style of tags. To deselect an option, just click the X icon in the tag.

How to use it:

1. Create a multiple select box on the page and define the placeholder text in the data-placeholder attribute:

<select multiple data-placeholder="Select Languages">
  <option>Python</option>
  <option selected>JavaScript</option>
  <option>C/C++</option>
  <option>Java</option>
  <option>Kotlin</option>
  <option>PHP</option>
  <option>Scala</option>
  <option>Vue.js</option>
  <option>Angular</option>
  <option>React</option>
</select>

2. Load the needed jQuery library in the document.

<script src="/path/to/cdn/jquery.min.js"></script>

3. Convert the select box into a tags input.

$(document).ready(function () {

  var select = $('select[multiple]');
  var options = select.find('option');

  var div = $('<div />').addClass('selectMultiple');
  var active = $('<div />');
  var list = $('<ul />');
  var placeholder = select.data('placeholder');

  var span = $('<span />').text(placeholder).appendTo(active);

  options.each(function () {
    var text = $(this).text();
    if ($(this).is(':selected')) {
      active.append($('<a />').html('<em>' + text + '</em><i></i>'));
      span.addClass('hide');
    } else {
      list.append($('<li />').html(text));
    }
  });

  active.append($('<div />').addClass('arrow'));
  div.append(active).append(list);

  select.wrap(div);

  $(document).on('click', '.selectMultiple ul li', function (e) {
    var select = $(this).parent().parent();
    var li = $(this);
    if (!select.hasClass('clicked')) {
      select.addClass('clicked');
      li.prev().addClass('beforeRemove');
      li.next().addClass('afterRemove');
      li.addClass('remove');
      var a = $('<a />').addClass('notShown').html('<em>' + li.text() + '</em><i></i>').hide().appendTo(select.children('div'));
      a.slideDown(400, function () {
        setTimeout(function () {
          a.addClass('shown');
          select.children('div').children('span').addClass('hide');
          select.find('option:contains(' + li.text() + ')').prop('selected', true);
        }, 500);
      });
      setTimeout(function () {
        if (li.prev().is(':last-child')) {
          li.prev().removeClass('beforeRemove');
        }
        if (li.next().is(':first-child')) {
          li.next().removeClass('afterRemove');
        }
        setTimeout(function () {
          li.prev().removeClass('beforeRemove');
          li.next().removeClass('afterRemove');
        }, 200);

        li.slideUp(400, function () {
          li.remove();
          select.removeClass('clicked');
        });
      }, 600);
    }
  });

  $(document).on('click', '.selectMultiple > div a', function (e) {
    var select = $(this).parent().parent();
    var self = $(this);
    self.removeClass().addClass('remove');
    select.addClass('open');
    setTimeout(function () {
      self.addClass('disappear');
      setTimeout(function () {
        self.animate({
          width: 0,
          height: 0,
          padding: 0,
          margin: 0
        }, 300, function () {
          var li = $('<li />').text(self.children('em').text()).addClass('notShown').appendTo(select.find('ul'));
          li.slideDown(400, function () {
            li.addClass('show');
            setTimeout(function () {
              select.find('option:contains(' + self.children('em').text() + ')').prop('selected', false);
              if (!select.find('option:selected').length) {
                select.children('div').children('span').removeClass('hide');
              }
              li.removeClass();
            }, 400);
          });
          self.remove();
        })
      }, 300);
    }, 400);
  });

  $(document).on('click', '.selectMultiple > div .arrow, .selectMultiple > div span', function (e) {
    $(this).parent().parent().toggleClass('open');
  });

});
