This article will take you to learn more about the multi-selection and fuzzy query drop-down boxes in bootstrap-select. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.
The previous blogger encountered a problem in actual development, that is, it needs to support both multiple selection and simultaneous The drop-down control for fuzzy query is the well-known and powerful drop-down box plug-in bootstrap-select2. The blogger also referred to it at the time, but found that its multi-select effect was relatively poor, similar to this,
Such a multi-select control must be long enough. If the selection exceeds a certain limit, the style will collapse. You know~ I accidentally discovered the bootstrap-select plug-in later. , I instantly realized that it was very high-end! It supports both single selection and multiple selection. The most amazing thing is that it even comes with a fuzzy query function! Let me show you the cool effects first:
It’s a pity not to use such a control. Later, the blogger found a lot of documents and blog references. , but I found that many of them did not clearly explain the specific usage. They just gave a simple example, which did not have much reference value. The blogger made a clear usage of bootstrap-select by studying the relevant documents on the official website and combining it with his own development experience. The summary is for your reference.

to control the display of the selected value
The following 4 values are available:
values: Comma-separated list of selected values (system default);
</blockquote><blockquote><p>2.<code>count： 如果选择了一个项，则显示选项值。如果选择多于一个，则显示所选项的数量,如选择2个，则下拉框显示2个已被选中；
3.
count > x： 当count的值小于x时，展示逗号分隔的选定值列表;当count>x时，显示x个被选中；
4.
static：无论选中什么，都只展示默认的选中文本。 下面给几个简单示例
<select class="selectpicker" multiple data-selected-text-format="count"> <option>Mustard</option> <option>Ketchup</option> <option>Relish</option> <option>Onions</option> </select>
效果展示
<select class="selectpicker" multiple data-selected-text-format="count>3"> <option>Mustard</option> <option>Ketchup</option> <option>Relish</option> <option>Onions</option> </select>
效果展示
data-style来设置按钮的样式<select class="selectpicker" data-style="btn-primary"> ... </select> <select class="selectpicker" data-style="btn-info"> ... </select> <select class="selectpicker" data-style="btn-success"> ... </select> <select class="selectpicker" data-style="btn-warning"> ... </select> <select class="selectpicker" data-style="btn-danger"> ... </select>

效果展示
.special {
font-weight: bold !important;
color: #fff !important;
background: #bc0000 !important;

}
<select class="selectpicker">
<option>Mustard</option>
<option class="special">Ketchup</option>
<option style="background: #5cb85c; color: #fff;">Relish</option>
</select>效果展示
1.引用bootstrap的样式
<div class="row">
<div class="col-xs-3">
<div class="form-group">
<select class="selectpicker form-control">
<option>Mustard</option>
<option>Ketchup</option>
<option>Relish</option>
</select>
</div>
</div>
</div>2.使用data-width属性，来定义宽度，可选的值有以下4个auto：select的宽度由option中内容宽度最宽的哪个决定；fit：select的宽度由实际选中的option的宽度决定；100px：select的宽度定义为100px；50%：select的宽度设置为父容器宽度的50%。
<select class="selectpicker" data-width="auto">
<option>cow</option>
<option>bullaaaaaaaaaaaa</option>
<option>ASD</option>
<option>Bla</option>
<option>Ble</option>
</select>
<select class="selectpicker" data-width="fit">
<option>cow</option>
<option>bullaaaaaaaaaaaa</option>
<option>ASD</option>
<option>Bla</option>
<option>Ble</option>
</select>
<select class="selectpicker" data-width="100px">
<option>cow</option>
<option>bull</option>
<option>ASD</option>
<option selected>Bla</option>
<option>Ble</option>
</select>
<select class="selectpicker" data-width="50%">
<option>cow</option>
<option>bull</option>
<option>ASD</option>
<option selected>Bla</option>
<option>Ble</option>
</select>效果展示：从左至右依次为“auto”,“fit","100px","50%"。
1.添加图标
用data-icon给option添加小图标，实现比较炫酷的效果
<select class="selectpicker"> <option data-icon="glyphicon-heart">Ketchup</option> <option data-icon="glyphicon glyphicon-th-large">Mustard</option> <option data-icon="glyphicon glyphicon-home">Relish</option> </select>
效果展示
如果想要获取更多样式可参考bootstrap官网的图标库，给个网址www.runoob.com/bootstrap/b…
2.插入HTML
用data-content可以在option中插入html元素,实现想要的效果。
<select class="selectpicker"> <option data-content="<span class='label label-success'>Relish</span>">Relish</option> </select>
效果展示
3.插入二级标题
用data-subtext实现二级标题，实现提示或者其他效果，如果要在select中也展示二级标题,要在初始化selectpicker时要设置showSubtext为true。
<select class="selectpicker" data-size="5">
<option data-subtext="Heinz">Ketchup</option>
<option data-subtext="ble">Mustard</option>
<option data-subtext="com">Relish</option>
</select>效果展示
$('.selectpicker').selectpicker({
'selectedText':'cat',
'showSubtext':true
})
<select class="selectpicker" data-size="5">
<option data-subtext="Heinz">Ketchup</option>
<option data-subtext="ble">Mustard</option>
<option data-subtext="com">Relish</option>
</select>效果展示
1.菜单显示项大小
通过data-size属性来限制菜单显示的条数，比如说option有8条，我们只展示5条,其余的通过滚动条显示。
<select class="selectpicker" data-size="5">
<option>apple</option>
<option>banana</option>
<option>group</option>
<option>orange</option>
<option>cherry</option>
<option>mango</option>
<option>pineapple</option>
<option>lychee</option>
</select>效果展示(只展示前5个，后面的可以拖动滚动条查看)
2.全选和全不选
通过设置data-actions-box="true"来添加全选和全不选的按钮
<select class="selectpicker" multiple data-actions-box="true"> <option>Mustard</option> <option>Ketchup</option> <option>Relish</option> </select>
效果展示
当然这个按钮的文本也是可以自定制的 只需要在初始化时设置即可
$('.selectpicker').selectpicker({
'selectedText':'cat',
'noneSelectedText':'请选择',
'deselectAllText':'全不选',
'selectAllText': '全选',
})效果展示
3.添加数据分割线
设置data-divider="true"添加数据分割线。
<select class="selectpicker" data-size="5"> <option>Mustrad</option> <option >Ketchup</option> <option >Relish</option> <option data-divider="true"></option> <option>Mustrad</option> <option >Ketchup</option> <option >Relish</option> </select>
效果展示
4.添加菜单头
用data-header为下拉菜单设置菜单头
<select class="selectpicker" data-header="Select a condiment"> <option>Mustard</option> <option>Ketchup</option> <option>Relish</option> </select>
效果展示
5.设置菜单的上浮或者下浮
通过设置dropupAuto来设置菜单的上下浮动，dropupAuto默认为true，自动确定是否应显示的菜单上面或下面的选择框，如果设置为false，系统会加入一个dropup样式的上拉框。
$('.selectpicker').selectpicker({
'selectedText':'cat',
'dropupAuto':false
})
<select class="selectpicker dropup">
<option>Mustard</option>
<option>Ketchup</option>
<option>Relish</option>
</select>效果展示
在对应的控件上加入disabled即可实现
1.设置select不可用
这里select按钮失效，不能点击
<select class="selectpicker" disabled> <option>Mustard</option> <option>Ketchup</option> <option>Relish</option> </select>
效果展示
2.设置option不可用
这里option设置属性为disabled的将无法选中
<select class="selectpicker"> <option>Mustard</option> <option disabled>Ketchup</option> <option>Relish</option> </select>
效果展示
3.设置optiongroup不可用 这里是一个optiongroup将无法选中
<select class="selectpicker test">
<optgroup label="Picnic" disabled>
<option>Mustard</option>
<option>Ketchup</option>
<option>Relish</option>
</optgroup>
<optgroup label="Camping">
<option>Tent</option>
<option>Flashlight</option>
<option>Toilet Paper</option>
</optgroup>
</select>效果展示
好的，这里我们基本上把官方的应用示例解读完毕，当然如果有疑问可以自己亲自去验证或者咨询博主，想实现自己想要的效果就要多加摸索和实践，只要明白其中的规则就能触类旁通了。第一篇关于bootstrap-select的官方示例文档的解读，如果想了解更多bootstrap-select的用法，可以关注我后面的博客哦。
