What is the best way to have react-bootstrap's Dropdown automatically open when hovering your mouse over it?

Question

What is the best way to have react-bootstrap's Dropdown automatically open when hovering your mouse over it?

Looking for a simple solution. I want the dropdown to open when hovering over it, rather than clicking on it.

Here is my current code:

    <Nav>
      <NavDropdown
        onMouseEnter = {()=> isOpen=true}
        open={isOpen}
        noCaret
        id="language-switcher-container"
      >
        <MenuItem>Only one Item</MenuItem>
      </NavDropdown>
    </Nav>

I tried using onMouseEnter but it didn't work. Can anyone help me solve this issue? What attribute should I pass in to make it work?

You can find more information on the React Bootstrap API page here.

class Navigation extends React.Component {

  constructor(props) {
    super(props)
    this.state = { isOpen: false }
  }

  expandNav = () => {
    this.setState({ isOpen: true })
  }

  collapseNav = () => {
     this.setState({ isOpen: false })
  }

  render() {
    return (
       <Navigation>
        <NavDropdown
          onMouseEnter = { this.expandNav }
          onMouseLeave = { this.collapseNav }
          open={ this.state.isOpen }
          noCaret
          id="language-switcher-container"
        >
          <MenuItem>Just one Item</MenuItem>
        </NavDropdown>
      </Navigation>
    )
  }
}

I hope that resolves your problem.

After encountering this issue myself recently, I discovered that in order for react-bootstrap to work properly, you need to include both the bootstrap CSS and a specific parameter. First, make sure to add the following custom CSS:

.dropdown:hover>.dropdown-menu {
  display: block;
}

Additionally, don't forget to include the renderMenuOnMount={true} parameter for the child elements to be rendered upon loading:

<NavDropdown renderMenuOnMount={true}>
  <NavDropdown.Item href="#">Item #1</NavDropdown.Item>
</NavDropdown>

It really is as straightforward as that :)

Taking inspiration from Rei Dien's response, I have implemented a solution using React Hooks.

const MenuOption = () => {
  const [menuOpen, toggleMenuOpen] = useState(false);

  return (
    <Dropdown
      onMouseEnter={() => {
        toggleMenuOpen(true);
      }}
      onMouseLeave={() => {
        toggleMenuOpen(false);
      }}
      show={menuOpen}
    >
      <Dropdown.Toggle>
        Menu
      </Dropdown.Toggle>

      <Dropdown.Menu>
        <Dropdown.Item href="#">Menu!!!</Dropdown.Item>
      </Dropdown.Menu>
    </Dropdown>
  );
};

This might not be the most elegant solution, but it gets the job done when it comes to making sure my app continues to function properly after an update.

Since the recent update, I've noticed that the dropdown-menu doesn't appear until the button is actually clicked.

In order to address this issue, I've implemented the following CSS:

.dropdown:hover .dropdown-menu {
    display: block;
}

Additionally, I included the following code snippet in my component:

  componentDidMount() {
    // TODO: Find a way to automatically render the menu without requiring a click
    const hiddenNavToggle = document.getElementById('navbar__hamburger_wrapper-hidden_click')
    hiddenNavToggle.click()
    hiddenNavToggle.click()
  }

To trigger the menu rendering without clicking, I simply added a wrapping div with the specified ID.

If anyone has a better solution, I'm all ears!

Another approach

const CustomDropDown = ({ children, ...restProps }) => {
    const [isOpen, setIsOpen] = useState(false);
    
    return (
        <Dropdown {...restProps} show={isOpen} onMouseEnter={() => setIsOpen(true)} onMouseLeave={() => setIsOpen(false)}

            {children}

You have the option to recreate this hover effect from https://codepen.io/bsngr/pen/frDqh by utilizing the following JavaScript code:

$('ul.nav li.dropdown').hover(function() {
  $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeIn(500);
}, function() {
  $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeOut(500);
});

Another alternative is to integrate a plugin like the one available at https://github.com/CWSpear/bootstrap-hover-dropdown

EDIT: These are effective solutions for bootstrap, but considering you mentioned using react, I haven't personally worked with that yet. Although, I believe the provided JavaScript code can be adjusted to fit your requirements.
