javascript - 推特 Bootstrap 选择菜单将其他元素推到下面

Question

这就是正在发生的事情。我为此选择使用 bootsrap-select。

它的CSS是

/*!

.bootstrap-select.btn-group,
.bootstrap-select.btn-group[class*="span"] {

js是

 <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
      <script src="js/bootstrap.min.js"></script>
      <script src="js/bootstrap-select.js"></script>
      <script type="text/javascript">
    $(document).ready(function() {
  $('.selectpicker').selectpicker({
    style: 'btn btn-white btn-sm'
  });
});
      </script>

为什么它向下拉伸(stretch)其他元素？为什么会这样？html是

 <div class="form-group">

                      <label class="control-label" style="display:inline;">Expiry</label>

               <div>                



    <select class="selectpicker" id="expiry_month" name="expiry_month">
    <option selected>Select Month</option>
    <option value="01">January</option>
    <option value="02">February</option>
    <option value="03">March</option>
    <option value="04">April</option>
    <option value="05">May</option>
    <option value="06">June</option>
    <option value="07">July</option>
    <option value="08">August</option>
    <option value="09">September</option>
    <option value="10">October</option>
    <option value="11">November</option>
    <option value="12">December</option>
    </select>






    <select class="selectpicker" id="expiry_year" name="expiry_year">
    <option selected>Select Year</option>
    <option value="2012">2012</option>
    <option value="2013">2013</option>
    <option value="2014">2014</option>
    <option value="2015">2015</option>
    <option value="2016">2016</option>
    <option value="2017">2017</option>
    <option value="2018">2018</option>
    <option value="2019">2019</option>
    <option value="2020">2020</option>
    <option value="2021">2021</option>
    <option value="2022">2022</option>
    <option value="2023">2023</option>
    <option value="2024">2024</option>
    <option value="2025">2025</option>
    <option value="2026">2026</option>                          <option value="2027">2027</option>
    <option value="2028">2028</option>
    <option value="2029">2029</option>
    <option value="2030">2030</option>
    <option value="2031">2031</option>
    <option value="2032">2032</option>
    <option value="2033">2033</option>
    <option value="2034">2034</option>
    <option value="2035">2035</option>
    <option value="2036">2036</option>
    </select>





    </div>
    </div>

它的 css 有问题吗？或者我可以在 javascript 中使用任何规范吗？我正在使用这个 http://silviomoreto.github.io/bootstrap-select/

Answer 1

这是 css 和 javascript 的问题。为什么你不尝试使用 Select2 http://ivaynberg.github.io/select2/ ？它没有任何问题。我已经使用它很长时间了。
