I have an issue that I can not take out the value of Dropdown to setState or something like that. Does everyone know how to fix it? I tried to access on it by onChange but still not working.

The code is below:

const menu = (
    <Menu onSelect={(e) => console.log(e)}>
      <Menu.Item>
        <a target="_blank" rel="noopener noreferrer">
          Recommended
        </a>
      </Menu.Item>
      <Menu.Item>
        <a target="_blank" rel="noopener noreferrer">
          Newest
        </a>
      </Menu.Item>
      <Menu.Item>
        <a target="_blank" rel="noopener noreferrer">
          Lowest Price
        </a>
      </Menu.Item>
      <Menu.Item>
        <a target="_blank" rel="noopener noreferrer">
          Highest Price
        </a>
      </Menu.Item>
    </Menu>
  );


<Dropdown overlay={menu1} trigger={['click']}>
            <a
              className="ant-dropdown-link"
              onClick={(e) => e.preventDefault()}
              style={{ color: '#d46b08', fontWeight: 'bold' }}
            >
              PRICE <DownOutlined />
            </a>
</Dropdown> ```

In order to get the value of the selected menu on dropdown, you need to assign a key on each menu item and then you can use onClick prop of the Menu component to get the value or the key.

const handleClick = ({key}) => {
  console.log(key)
  //you can perform setState here
}

const menu = (
  <Menu onClick={handleClick}>
    <Menu.Item key="Recommend">Recommend</Menu.Item>
    <Menu.Item key="Newest">Newest</Menu.Item>
    <Menu.Item key="Lowest Price">Lowest Price</Menu.Item>
    <Menu.Item key="Highest Price">Highest Price</Menu.Item>
  </Menu>
);

<Dropdown overlay={menu} trigger={["click"]}>
    <a
      className="ant-dropdown-link"
      onClick={(e) => e.preventDefault()}
      style={{ color: "#d46b08", fontWeight: "bold" }}
    >
      PRICE <DownOutlined />
    </a>
</Dropdown>

The Dropdown component does not call any onChange property. It has onVisibleChange property that gets called every time the "dropdown trigger" (be it hover, click, right-click) is done. Do something like this:

const SomeComponent = _props =>
{
  const [visible, setVisible] = React.useState(false);
  
  return (<Dropdown overlay={menu} visible={visible} onVisibleChange={isVisible => setVisible(isVisible)} >
    <a className="ant-dropdown-link" onClick={e => e.preventDefault()}>
      Hover me <DownOutlined />
    </a>
  </Dropdown>);
}
