Html 引导内容不是'；用数据进行扩展

最后一个输入被内容隐藏，我正在使用twitter引导。我肯定我的班级排在正确的位置了

它只是一个带有表单和输入的简单col

你们能看到什么东西可以说明为什么它不展开，因为如果我使用我现在所在的行，col应该随着数据展开

    <div class="row">
    <div class="col-lg-12">
<div class="col-lg-12">
    <div class="ibox">
        <div class="ibox-title">

                    </div>

                </fieldset>

必须严格地将具有
列sm-*
类的元素作为具有
行
类的元素的子元素。例如，请参见类
buyitnow

<div class="row">
  .
  .
  .
  <div class="buyitnow">
     <div class="form-group col-sm-3">


.
.
.

应该是这样的

<div class="row">
  .
  .
  .
  <div class="buyitnow col-sm-3">
     <div class="form-group">


.
.
.

以此类推，下一个代码是您的代码的更好的格式化版本，因此您可以更好地理解这个想法

你能编一把小提琴把问题再现出来吗？仅从您的代码中，我看不到任何可以“隐藏”输入（字段）的内容。
