How to Implement Dropdown on Hover in React with Ant Design 5

In this tutorial, we’ll create a dropdown-on-hover feature in React using Ant Design 5. First, you’ll need to set up a React project with Ant Design 5.

install & setup vite + react + typescript + ant design 5

1. Create a simple dropdown-on-hover in React using Ant Design 5 components such as MenuProps, Dropdown, Space, and the icons DownOutlined and SmileOutlined.

import React from 'react';
import { DownOutlined, SmileOutlined } from '@ant-design/icons';
import type { MenuProps } from 'antd';
import { Dropdown, Space } from 'antd';

const items: MenuProps['items'] = [
  {
    key: '1',
    label: (
      <a target="_blank" rel="noopener noreferrer" href="https://www.antgroup.com">
        1st menu item
      </a>
    ),
  },
  {
    key: '2',
    label: (
      <a target="_blank" rel="noopener noreferrer" href="https://www.aliyun.com">
        2nd menu item (disabled)
      </a>
    ),
    icon: <SmileOutlined />,
    disabled: true,
  },
  {
    key: '3',
    label: (
      <a target="_blank" rel="noopener noreferrer" href="https://www.luohanacademy.com">
        3rd menu item (disabled)
      </a>
    ),
    disabled: true,
  },
  {
    key: '4',
    danger: true,
    label: 'a danger item',
  },
];

const App: React.FC = () => (
  <Dropdown menu={{ items }}>
    <a onClick={(e) => e.preventDefault()}>
      <Space>
        Hover me
        <DownOutlined />
      </Space>
    </a>
  </Dropdown>
);

export default App;

2. Implement a dropdown-on-hover feature in React with Ant Design 5, showcasing placements at the top, left, right, bottom, bottom left, and bottom right.

import React from 'react';
import type { MenuProps } from 'antd';
import { Button, Dropdown, Space } from 'antd';

const items: MenuProps['items'] = [
  {
    key: '1',
    label: (
      <a target="_blank" rel="noopener noreferrer" href="https://www.antgroup.com">
        1st menu item
      </a>
    ),
  },
  {
    key: '2',
    label: (
      <a target="_blank" rel="noopener noreferrer" href="https://www.aliyun.com">
        2nd menu item
      </a>
    ),
  },
  {
    key: '3',
    label: (
      <a target="_blank" rel="noopener noreferrer" href="https://www.luohanacademy.com">
        3rd menu item
      </a>
    ),
  },
];

const App: React.FC = () => (
  <Space direction="vertical">
    <Space wrap>
      <Dropdown menu={{ items }} placement="bottomLeft">
        <Button>bottomLeft</Button>
      </Dropdown>
      <Dropdown menu={{ items }} placement="bottom">
        <Button>bottom</Button>
      </Dropdown>
      <Dropdown menu={{ items }} placement="bottomRight">
        <Button>bottomRight</Button>
      </Dropdown>
    </Space>
    <Space wrap>
      <Dropdown menu={{ items }} placement="topLeft">
        <Button>topLeft</Button>
      </Dropdown>
      <Dropdown menu={{ items }} placement="top">
        <Button>top</Button>
      </Dropdown>
      <Dropdown menu={{ items }} placement="topRight">
        <Button>topRight</Button>
      </Dropdown>
    </Space>
  </Space>
);

export default App;

3. Create a dropdown-on-hover feature in React using Ant Design 5 with a menu.

import React from 'react';
import { DownOutlined, UserOutlined } from '@ant-design/icons';
import type { MenuProps } from 'antd';
import { Button, Dropdown, message, Space, Tooltip } from 'antd';

const handleButtonClick = (e: React.MouseEvent<HTMLButtonElement>) => {
  message.info('Click on left button.');
  console.log('click left button', e);
};

const handleMenuClick: MenuProps['onClick'] = (e) => {
  message.info('Click on menu item.');
  console.log('click', e);
};

const items: MenuProps['items'] = [
  {
    label: '1st menu item',
    key: '1',
    icon: <UserOutlined />,
  },
  {
    label: '2nd menu item',
    key: '2',
    icon: <UserOutlined />,
  },
  {
    label: '3rd menu item',
    key: '3',
    icon: <UserOutlined />,
    danger: true,
  },
  {
    label: '4rd menu item',
    key: '4',
    icon: <UserOutlined />,
    danger: true,
    disabled: true,
  },
];

const menuProps = {
  items,
  onClick: handleMenuClick,
};

const App: React.FC = () => (
  <Space wrap>
    <Dropdown.Button menu={menuProps} onClick={handleButtonClick}>
      Dropdown
    </Dropdown.Button>
    <Dropdown.Button menu={menuProps} placement="bottom" icon={<UserOutlined />}>
      Dropdown
    </Dropdown.Button>
    <Dropdown.Button menu={menuProps} onClick={handleButtonClick} disabled>
      Dropdown
    </Dropdown.Button>
    <Dropdown.Button
      menu={menuProps}
      buttonsRender={([leftButton, rightButton]) => [
        <Tooltip title="tooltip" key="leftButton">
          {leftButton}
        </Tooltip>,
        React.cloneElement(rightButton as React.ReactElement<any, string>, { loading: true }),
      ]}
    >
      With Tooltip
    </Dropdown.Button>
    <Dropdown menu={menuProps}>
      <Button>
        <Space>
          Button
          <DownOutlined />
        </Space>
      </Button>
    </Dropdown>
    <Dropdown.Button menu={menuProps} onClick={handleButtonClick} danger>
      Danger
    </Dropdown.Button>
  </Space>
);

export default App;
