Twitter bootstrap 形成水平引导

我用的是一个引导式的horitonzal表单，这很有效 但是我每行有3个表单，但是我想有一个表单来获得与有几行的水平表单相同的效果。但是我每行有3个表单，但是我想有一个表单来获得与有几行的水平表单相同的效果

我的想法是进行验证，为此我需要在一个表单中包含所有输入

<form class="form-horizontal" name="frm1" role="form">
    <div class="form-group">

        <label for="txtNombre" class="col-sm-2 control-label">Nombre</label>
        <div class="col-xs-3">
            <input type="text" class="form-control" id="txtNombre" ng-model="model.nombre" placeholder="Rut">
        </div>


        <label for="txtRut" class="col-sm-1 control-label">Rut</label>
        <div class="col-xs-2">
            <input type="text" class="form-control" id="txtRut" placeholder="Rut">
        </div>
        <div class="col-sm-1">
            <input type="password" id="txtDv" class="form-control" id="inputPassword3" placeholder="Dv">
