bootstrap的<select ####>{foreach}这个片段什么意思

<div class="content-head mgb10">
                            <div class="form-group">
                                <label  class="sr-only"></label>
                                <input type="text" class="form-control" id="sn-val" placeholder="请输入单据号">

name是数据源，item是循环变量，这只是遍历数据源，渲染数据而已
