为什么bootstrap不把选择放在一行?它们在有界的列中?

像这样检查你需要的DEMO

    <div class="container"> 
  <h2>Gratisofferte</h2>
   <form role="form">
    <div class="form-group col-md-3">
            <label>Aktuelle Adresse</label>
            <input class="form-control " placeholder="z.B. Paradiesstrasse 10" type="text" id="n_adr">
                <span id="fname1" class="glyphicon form-control-feedback glyphicon-ok"></span>
</div>  <div class="form-group col-md-2">
            <label>PLZ</label>
            <input class="leftstraight form-control" placeholder="PLZ" type="text" id="n_plz">
        </div>
          <div class="form-group col-md-2">

        </div>
    <div class="form-group col-md-1">

Answer 2

答案是christina在这篇文章中给出的

两个输入相同的表单列占用所有单元格宽度

解决方案在于行嵌套，因此使其比12部分网格更薄=更精确。所以你在4-4-4中放了第一个网格，然后你可以在每个网格中再次创建一个网格。这样你就可以实现超过12层的网格。例如，您可以将最后一列分割为5-5-1，这将导致13% - 13%和2.7%的总分解(= 0.33的12-tel)。

<div class="container">
  <h2>Gratisofferte</h2>
  <form role="form" class="form-horizontal">
 <div id="form1">
    <div class="form-group ">
		<div class="col-sm-4 col-xs-5">
			<label>Aktuelle Adresse</label>
            <div class=" has-feedback has-success">

                <span id="fname1" class="glyphicon form-control-feedback glyphicon-ok"></span></div>
</div>
		<div class="col-sm-3 col-xs-4" style="margin-left:-30px;">
			<label>PLZ</label>
            <input class="leftstraight form-control" placeholder="PLZ" type="text" id="n_plz">

至于这个问题，我不知道有什么方法可以把上面的标签放在适当的地方，而不把输入标签组合在一个单独的col中，也许只有自定义css。
