问题:

I am trying to change the width of the selectpicker box that shows selected options, but no matter what I try I am unable to change it, nor am I able to change the color of the box.

Any ideas or suggestions are appreciated.

Code Snippet for what I have assuming should change the box width is as follows (as you can see I set it all the way down to 25 but the width is still quite wide):

.selectpicker {
width: 25px;

Code snippet you can run:

<script>
  $(function() {
    $('[data-toggle="tooltip"]').tooltip()
  }) 
</script>

<script type = "text/javascript">
  $(window).on('load', function() {
      $('.selectpicker').selectpicker({
      'selectedText': 'cat'
      });
      // $('.selectpicker').selectpicker('hide');  
  }); 
</script>
.text-muted {
  font-size: small;
}

.text-bold {
  font-weight: bold;
  font-size: small;
}

.button {
  background-color: #008CBA;
  /* Light Blue */
  border: none;
  color: white;
  text-align: center;
  text-decoration: none;
  display: inline-block;
  font-size: 11px;
  margin: 4px 2px;
  cursor: pointer;
  border-radius: 4px;
  padding: 6px 10px;
}

.button2 {
  background-color: #008CBA;
  /* Light Blue */
  border: none;
  color: white;
  text-align: center;
  text-decoration: none;
  display: inline-block;
  font-size: 11px;
  margin: 8px 2px;
  cursor: pointer;
  border-radius: 4px;
  padding: 6px 10px;
}

回答1:

Use data-content attribute in select option. For example:

<select class="selectpicker form-control" data-live-search="true" id="subject_teacher_drop_down">
    <option data-content="English">English</option>
    <option data-content="Methodology of social...">Methodology of social science with special reference to economics</option>
</select>


回答2:

Your code snippet example in question doesn't work at all. I did some cleanup and prepared an another one below, and also JSFiddle.

  1. To change width you should adjust .bootstrap-select class:
.bootstrap-select {
  width: 330px !important;
}
  1. It is not so easy to change the button's color properly. Button has different states, all programmed in bootstrap.css. I have take all entries for the btn-info class, renamed them to btn-custom and changed colors for the .btn-custom CSS entry only:
.btn-custom {
  color: #fff;
  background-color: #008CBA;
  border-color: #008CBA;
}

You should review all other btn-custom colors and adjust accordingly.

  1. Use your select as the following:
<select class="selectpicker" data-style="btn-custom" multiple data-max-options="4" data-actions-box="true">

The whole working example:

$(function() {
    $('[data-toggle="tooltip"]').tooltip()
  });

  $('.selectpicker').selectpicker({
    'selectedText': 'cat'
  });

  // $('.selectpicker').selectpicker('hide');
.text-muted {
  font-size: small;
}

.text-bold {
  font-weight: bold;
  font-size: small;
}

.button {
  background-color: #008CBA;
  /* Light Blue */
  border: none;
  color: white;
  text-align: center;
  text-decoration: none;
  display: inline-block;
  font-size: 11px;
  margin: 4px 2px;
  cursor: pointer;
  border-radius: 4px;
  padding: 6px 10px;
}

.button2 {
  background-color: #008CBA;
  /* Light Blue */
  border: none;
  color: white;
  text-align: center;
  text-decoration: none;
  display: inline-block;
  font-size: 11px;
  margin: 8px 2px;
  cursor: pointer;
  border-radius: 4px;
  padding: 6px 10px;
}

.button2:hover {
  background-color: #008CBA;
  box-shadow: 0 12px 16px 0 rgba(0, 0, 0, 0.24), 0 17px 30px 0 rgba(0, 0, 0, 0.19);
