如何设置Antd SubMenu仅在点击时展开而非鼠标悬停？

当前使用Antd的SubMenu时，默认鼠标悬停就会展开子菜单，需要修改为仅点击「Navigation Three」或「Navigation Four」才展开子菜单。

解决方法 #

Antd的Menu组件提供了triggerSubMenuAction属性，将其设置为'click'即可改变子菜单的触发方式（默认值为'hover'）。只需在<Menu>标签中添加该属性即可实现需求。

import React from "react";
import ReactDOM from "react-dom";
import "antd/dist/antd.css";
import { Menu, Icon } from "antd";

const { SubMenu } = Menu;

class Sider extends React.Component {
  state = {
    mode: "vertical",
    theme: "light"
  };

  render() {
    return (
      <div>
        <br />
        <br />
        <Menu
          style={{ width: 256 }}
          mode={this.state.mode}
          theme={this.state.theme}
          triggerSubMenuAction="click" // 添加该属性修改触发方式
        >
          <SubMenu
            key="sub1"
            title={
              <span>
                <Icon type="appstore" />
                <span>Navigation Three</span>
              </span>
            }
          >
            <Menu.Item key="3">Option 3</Menu.Item>
            <Menu.Item key="4">Option 4</Menu.Item>
            <SubMenu key="sub1-2" title="Submenu">
              <Menu.Item key="5">Option 5</Menu.Item>
              <Menu.Item key="6">Option 6</Menu.Item>
            </SubMenu>
          </SubMenu>
          <SubMenu
            key="sub2"
            title={
              <span>
                <Icon type="setting" />
                <span>Navigation Four</span>
              </span>
            }
          >
            <Menu.Item key="7">Option 7</Menu.Item>
            <Menu.Item key="8">Option 8</Menu.Item>
            <Menu.Item key="9">Option 9</Menu.Item>
            <Menu.Item key="10">Option 10</Menu.Item>
          </SubMenu>
        </Menu>
      </div>
    );
  }
}

ReactDOM.render(<Sider />, document.getElementById("container"));
