</form>
<div class="row">
<button class="btn btn-success btn-sm pull-right">+</button>
</div>
+按钮使用javascript动态地将
div.form-wrapper元素中的另一个与新的表单字段一起添加。它还会生成-按钮以动态删除表单。问题是-和+因为它们都被向右拉，所以它们出现在同一行中。我不想要那个。引导程序中的行类不能同时清除两者吗？ Here是以上内容的示例 最佳答案
您可以将另一个行元素添加到-按钮
<div class="row">
<button class="btn btn-danger btn-sm pull-right" id="2">-</button>
</div>
