jsantd多选下拉框一行展示的实现方式js大全

我们都知道antd的select多选时,如果下拉框宽度不足,则自动浮动到下一行将下拉框撑大,但是这回影响到页面的整体布局。我们期望的效果是,下拉框只显示一行的值,超出一行的部分自动隐藏。下面有2种方案来实现这个效果。下面有2种方案来实现这个效果。下面有2种方案来实现这个效果。1.利用浮动原理1.利用浮动原理
设置下拉框的最大高度为一行的高度,然后超出的部分隐藏。
.ant-select-selection--multiple {
max-height: 32px;
overflow: hidden;
}
.ant-select-selection--multiple {
max-height: 32px;
overflow: hidden;
}这种方式存在的弊端是如果有2个选项,一个很短一个很长,那么只能看到很短的值,长值被隐藏,会剩余很大的空白。2.flex布局2.flex布局
将下拉框选项放到一行显示,如果超出了下拉框长度则隐藏。默认的选项是采用float浮动显示的,所以我们要屏蔽掉浮动效果。
.ant-select-selection--multiple .ant-select-selection__rendered {
overflow: hidden;
}
.ant-select-selection--multiple .ant-select-selection__rendered ul {
display: flex;
flex-wrap: nowrap;
overflow: hidden;
float: left;
}
.ant-select-selection--multiple .ant-select-selection__choice {
float: none;
overflow: visible;
}
.ant-select-selection--multiple .ant-select-search--inline {
float: none;
position: absolute;
}
.ant-select-selection--multiple {
max-height: 32px;
overflow: hidden;
}
.ant-select-selection--multiple .ant-select-selection__rendered {
overflow: hidden;
}
.ant-select-selection--multiple .ant-select-selection__rendered ul {
display: flex;
flex-wrap: nowrap;
overflow: hidden;
float: left;
}
.ant-select-selection--multiple .ant-select-selection__choice {
float: none;
overflow: visible;
}
.ant-select-selection--multiple .ant-select-search--inline {
float: none;
position: absolute;
}
.ant-select-selection--multiple {
max-height: 32px;
overflow: hidden;
}
这里重写了下拉选项的样式,达到了目的,但是会存在另一个问题,因为下拉选项排成了不换行的一列,那么必须指定下拉框的长度为固定值,不能使用百分比,因为一旦选中的下拉值超出了屏幕宽度,那么他会自动撑大整个屏幕的宽度。补充知识:antd design Menu菜单下拉回调以及下拉列表时只能显示一个列表,其余关闭补充知识:补充知识:antd design Menu菜单下拉回调以及下拉列表时只能显示一个列表,其余关闭我做的是一个显示全国省市区的下拉列表:如下图这个下拉列表是三层嵌套的下拉列表,统计列表不能同时打开,一次只能点开一个。点击下拉时触发函数获得下一层级的下拉数据。代码如下:
render(){
let city=this.state.cityList.map(itemss=>(
key={itemss.id}
title={ {itemss.name}}
onTitleClick={this.getCountryList.bind(this,itemss.id,itemss.name)}
>
{
this.state.countryList.map(citem=>(
{citem.name}
))
}
));
const { startValue, endValue, endOpen } = this.state;
return(
collapsed={this.state.collapsed}
style={{backgroundColor:'#FFFFFF'}}
className=""
onCollapse={this.onCollapse}
openKeys={this.state.openKeys}--->根据this.state.openKeys的值去对应SubMenu的key值 从而展开此列表。
