Select2应用bootstrap input-lg

Question

如何在select2下拉列表中实现input-lg类？我的下拉菜单与输入元素的大小相同，这里有一类输入-lg，这是我到目前为止所拥有的

<div class="col-sm-4">
     <label for="mobile" class="control-label"><span class="text-danger">*</span> Nationality</label>
     <input type="text" id="nationality" name="nationality" class="form-control input-lg" />
</div>

<div class="col-sm-4 padding-minimum">
     <label for="mobile" class="control-label"><span class="text-danger">*</span> Gender</label>
     <select name="gender" id="gender" class="form-control select2-container input-lg step2-select" data-placeholder="Select Gender">
         <option></option>
         <option value="1">Male</option>
         <option value="0">Female</option>
     </select>
</div>

这是我的剧本

<script>
  $(document).ready(function(){
    $('select').select2();
  });
</script>

但似乎初始化下拉列表的大小与输入-lg类的输入字段的大小不同，尽管我在select元素上放置了一个input-lg类。有关如何实现这一点的任何想法？我只是希望select2与输入字段具有相同的高度

我使用select2版本4.0.0而css是版本3.5.2我认为

Answer 1

要使select输入的高度相等，请在CSS中进行以下更改，并从input-lg移除<select>选择器，这是不必要的，不使用它

$(document).ready(function () {
	$('select').select2();
});

.select2-container--default .select2-selection--single {
    height: 46px !important;
    padding: 10px 16px;
    font-size: 18px;
    line-height: 1.33;
    border-radius: 6px;
}
.select2-container--default .select2-selection--single .select2-selection__arrow b {
    top: 85% !important;
}
.select2-container--default .select2-selection--single .select2-selection__rendered {
    line-height: 26px !important;
}
.select2-container--default .select2-selection--single {
    border: 1px solid #CCC !important;
    box-shadow: 0px 1px 1px rgba(0, 0, 0, 0.075) inset;
    transition: border-color 0.15s ease-in-out 0s, box-shadow 0.15s ease-in-out 0s;
}

    <input type="text" id="nationality" name="nationality" class="form-control input-lg" />
</div>
<div class="col-sm-4 padding-minimum">
    <label for="mobile" class="control-label"><span class="text-danger">*</span> Gender</label>
    <select name="gender" id="gender" class="form-control select2-container step2-select" data-placeholder="Select Gender">
        <option></option>
        <option value="1">Male</option>
        <option value="0">Female</option>
    </select>
</div>

Answer 2

我发现这个dedicated CSS（select2-bootstrap-theme）工作得很好。

bower install select2-bootstrap-theme

<link rel="stylesheet" href="select2.css">
<link rel="stylesheet" href="select2-bootstrap.css">

$( "#dropdown" ).select2({
    theme: "bootstrap"
});

select2.full.js told to be required能够管理尺寸，但我似乎没有“完整”版本就可以使用

Answer 3

在你的css之前输入-lg +，然后再上课.select2-container example：`

.input-lg+.select2-container--default .select2-selection--single {
    height: 46px !important;
    padding: 10px 16px;
    font-size: 18px;
    line-height: 1.33;
    border-radius: 6px;
}
.input-lg+.select2-container--default .select2-selection--single .select2-selection__arrow b {
    top: 85% !important;
}
.input-lg+.select2-container--default .select2-selection--single .select2-selection__rendered {
    line-height: 26px !important;
}
.input-lg+.select2-container--default .select2-selection--single {
    border: 1px solid #CCC !important;
    box-shadow: 0px 1px 1px rgba(0, 0, 0, 0.075) inset;
    transition: border-color 0.15s ease-in-out 0s, box-shadow 0.15s ease-in-out 0s;
}

Answer 4

只需通过下载select2附加CSS

将select2设置为使用bootstrap主题即可

https://github.com/select2/select2-bootstrap-theme

<link href="js/select2-bootstrap-theme/dist/select2-bootstrap.min.css" rel="stylesheet">

然后在JS部分

$('.select2').select2({
    theme: "bootstrap"
});

（没有bootstrap-theme）

（使用bootstrap-theme）

Answer 5

虽然select2-bootstrap-theme用于Bootstrap v3，但您可以将其用于Bootstrap v4。

安装

  

$ npm install @ ttskch / select2-bootstrap4-theme

用法

<link rel="stylesheet" href="/path/to/select2.css">
<link rel="stylesheet" href="/path/to/select2-bootstrap4.css">

$('select').select2({
   theme: 'bootstrap4',
});

这是它的Demo
