Select2：使用引导网格

Question

我有以下代码。可以，但是输入很小。我希望它看起来像任何其他Bootstrap输入，即。填充整个div容器。我已经安装了Bootstrap主题。我尝试使用.form-control类。

<div class="row">
  <div class="col-12 col-md-6">
    <select class="states" name="states[]" multiple="multiple">
      <option value="AL">Alabama</option>
      <option value="WY">Wyoming</option>
    </select>
  </div>
</div>

$(function() {
  $(".states").select2({
    theme: "bootstrap"
  });
});

Answer 1

只需使用CSS.states{ width:100%; }

.row {
  background-color:lightgray;
}

.states{
  width:100%;
}
