Creating a dynamic React Bootstrap NavDropdown that opens on hover

I'm struggling to make a dropdown menu bar in React Bootstrap display the options when hovering over it. Despite my extensive search, all the solutions I found seem outdated and ineffective. Please reach out if you can help me solve this issue.

Below is the dropdown menu where I want to implement this change:

<Navbar>
  <NavDropdown title="Dropdown Menu">
    <NavDropdown.Item href="#action/3.1">Option 1</NavDropdown.Item>
    <NavDropdown.Item href="#action/3.1">Option 2</NavDropdown.Item>
  </NavDropdown>
</Navbar>

Additionally, here is a sandbox link showcasing the provided code snippet.

Answer №1

To utilize the show property, follow these steps:

import React, { Component, Fragment, useState } from "react";
import ReactDOM from "react-dom";
import { Navbar, Nav, NavDropdown } from "react-bootstrap";

const Header = props => {
  const [show, setShow] = useState(false);
  return (
    <Navbar>
      <NavDropdown
        title="Dropdown Menu"
        show={show}
        onMouseEnter={() => setShow(true)}
        onMouseLeave={() => setShow(false)}
      >
        <NavDropdown.Item href="#action/3.1">Option 1</NavDropdown.Item>
        <NavDropdown.Item href="#action/3.1">Option 2</NavDropdown.Item>
      </NavDropdown>
    </Navbar>
  );
};

function App() {
  return <Header />;
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

Here is the CSS solution: Simply include renderMenuOnMount={true} within your NavDropdown component as shown below:

<NavDropdown title={category} id={category} renderMenuOnMount={true}>
...list of menu items...
</NavDropdown>

In addition, apply the following CSS styling:

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