默认
自定义<select>
菜单只需要一个自定义类,.form-select
来触发自定义样式。由于浏览器的限制,自定义样式只限于<select>
的初始外观,而不能修改<option>
。
<select class="form-select" aria-label="Default select example">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
尺寸
还可以从大小自定义选择中进行选择,以匹配我们类似大小的文本输入。
<select class="form-select form-select-lg mb-3" aria-label=".form-select-lg example">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<select class="form-select form-select-sm" aria-label=".form-select-sm example">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
还支持 multiple
属性:
<select class="form-select" multiple aria-label="multiple select example">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
As is the size
attribute:
<select class="form-select" size="3" aria-label="size 3 select example">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
禁用(Disabled)
在选择上添加 disabled
布尔属性,使其呈现灰色外观并删除指针事件。
<select class="form-select" aria-label="Disabled select example" disabled>
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
