Question

我有搜索控件，我添加了textBox，select和button。

    <div class="col-md-10"> 
<div class="row">
        <div id="Search_Widget_tr3" class="input-group col-md-12">
            <input type="text" class="form-control" placeholder="enter title" id="homeSearchInput"/>
            <div class="input-group-btn clearfix">
                <select class="selectpicker" multiple title='Platforms' data-container="body" data-count-selected-text="Platforms" data-selected-text-format="count>0" data-style="btn btn-default" data-allOptionIsSelected="false">
                    <option value="All">All Platforms</option>
                    <option value="Mobile Phone;Tablet;Windows Phone;PlayStation Certified Device;Windows 8 App;PlayStation Mobile">Mobile App/Tablet</option>
                    <option value="Nintendo DS;Nintendo DSi;Nintendo 3DS">Nintendo DS/DSi/3DS</option>
                    <option value="PlayStation 3">PlayStation 3</option>
                    <option value="PlayStation 4">PlayStation 4</option>
                    <option value="PSP;PS Vita">PlayStation Vita/PSP</option>

                    <option value="Linux;Macintosh;PC DVD;PC DVD-ROM;Windows CE;Windows PC;Windows 8 App">Windows/Mac</option>
                    <option value="Xbox 360">Xbox 360</option>
                    <option value="Xbox One">Xbox One</option>

                </select>
                <button class="btn btn-default dropdown-toggle click-search" type="button" aria-expanded="false">
                    Search <span class="glyphicon glyphicon-search"></span>
                </button>
            </div><!-- /btn-group -->
        </div><!-- /input-group --> 

        </div>  </div>

问题：我无法使<select>响应;它的宽度是固定的。

当我想将它包装在某个容器中并将col-md-5设置为此包装器时，我在输入和选择之间丢失了圆角（我不想添加一些新的样式仅用于使角落圆角）

此处live example

Answer 1

简单解决方案：将类form-control添加到select元素

Answer 2

我查看了css以查看“保持”选择框打开的内容，发现它设置为220px宽度。

如果将其添加到自定义css中，它应该可以正常工作：

.bootstrap-select:not([class*=col-]):not([class*=form-control]):not(.input-group-btn) {
    width: auto;
}
