Any idea on how to hide/back to its original state when selecting the links inside offcanvas using react scroll?
Below is my code and also here is the sandbox code https://codesandbox.io/.
App.js
import React, { useState, useEffect } from "react";
import { BrowserRouter, Routes, Route } from "react-router-dom";
import HeaderContent from "./components/Header";
import Content from "./components/Content";
import "./styles.css";
export default function App() {
return (
<BrowserRouter>
<header>
<HeaderContent />
</header>
<main className="flex-shrink-0">
<React.Suspense fallback={<h6>Loading...</h6>}>
<Routes>
<Route path="/" element={<Content />} />
</Routes>
</React.Suspense>
</main>
</BrowserRouter>
);
}
Header.js
import React, { useState, useEffect } from "react";
import { Container, Offcanvas, Navbar, Nav, Image } from "react-bootstrap";
import { Link } from "react-scroll";
const Header = () => {
const offsetValue = -56;
return (
<>
<Navbar bg="dark" variant="dark" expand={false} fixed="top">
<Container fluid>
<Navbar.Brand href="#">Navbar Offcanvas</Navbar.Brand>
<Navbar.Toggle aria-controls="offcanvasNavbar" />
<Navbar.Offcanvas
id="offcanvasNavbar"
aria-labelledby="offcanvasNavbarLabel"
placement="end"
>
<Offcanvas.Header closeButton>
<Offcanvas.Title id="offcanvasNavbarLabel">
Offcanvas
</Offcanvas.Title>
</Offcanvas.Header>
<Offcanvas.Body>
<Nav className="justify-content-end flex-grow-1 pe-3 offcanvas--menu">

);
};
export default Header;

Im using the ff:

react-router-dom 6.2.2
react-scroll 1.8.7
react-bootstrap offcanvas 2.1.2 https://react-bootstrap.github.io/components/offcanvas/
I'm not sure if I missed something like useState/useEffect
or an attribute
to make it work.

Alternative for the acccepted answer, if you like to use HTML property to close the offcanvas nav.
You just need to add data-bs-dismiss="offcanvas"
to the offcanvas
. This will create a behaviour, which when we click the offcanvas wrapper it will close itself.
Example for a
tag:
<div class="offcanvas" data-bs-dismiss="offcanvas">
...
<div class="offcanvas-body">
<a href="/about">About</a>
</div>
</div>
This workaround works well with next/script
module.
For example:
<div class="offcanvas" data-bs-dismiss="offcanvas">
...
<div class="offcanvas-body">
<Link href="/about" data-bs-dismiss="offcanvas">About</Link>
</div>
</div>

I'm not a fan of bootstrap and I'm sure there's a more vanilla Javascript/boostrap method for achieving this, but here's a simple implementation using some local state.
show
state that can be toggled true/false.onClick
handler to the Navbar.Toggle
component to handle opening the OffCanvas
component.show
and onHide
props to the Navbar.Offcanvas
to handle showing/hiding the OffCanvas
component.onClick
handler to each Link
component to toggle the show
state.Code
const Header = () => {
const [show, setShow] = useState(false);
const offsetValue = -56;
const toggleOffCanvas = () => {
setShow((show) => !show);
};
return (
<>
<Navbar ... >
<Container fluid>
<Navbar.Brand href="#">Navbar Offcanvas</Navbar.Brand>
<Navbar.Toggle
aria-controls="offcanvasNavbar"
onClick={toggleOffCanvas}
/>
<Navbar.Offcanvas
...
show={show}
onHide={toggleOffCanvas}
>
<Offcanvas.Header closeButton>
...
</Offcanvas.Header>
<Offcanvas.Body>
<Nav className="justify-content-end flex-grow-1 pe-3 offcanvas--menu">
<Link
...
onClick={toggleOffCanvas}
>
Home
</Link>
<Link
...
onClick={toggleOffCanvas}
>
About
</Link>
<Link
...
onClick={toggleOffCanvas}
>
Contact
</Link>
</Nav>
</Offcanvas.Body>
</Navbar.Offcanvas>
</Container>
</Navbar>
</>
);
};
Simpler implementation using a React ref.
Navbar.OffCanvas
component.onClick
handler to access the attached ref, the backdrop
element, and simulate a click event.onClick
handler to each Link
component to toggle the Navbar.OffCanvas
component hidden.Code
const Header = () => {
const offCanvasRef = useRef();
const offsetValue = -56;
const closeOffCanvas = () => offCanvasRef.current.backdrop.click();
return (
<>
<Navbar bg="dark" variant="dark" expand={false} fixed="top">
<Container fluid>
<Navbar.Brand href="#">Navbar Offcanvas</Navbar.Brand>
<Navbar.Toggle aria-controls="offcanvasNavbar" />
<Navbar.Offcanvas
ref={offCanvasRef}
...
>
<Offcanvas.Header closeButton>
...
</Offcanvas.Header>
<Offcanvas.Body>
<Nav className="justify-content-end flex-grow-1 pe-3 offcanvas--menu">
<Link
...
onClick={closeOffCanvas}
>
Home
</Link>
<Link
...
className="p-3 border-bottom border-dark text-decoration-none"
onClick={closeOffCanvas}
>
About
</Link>
<Link
...
onClick={closeOffCanvas}
>
Contact
</Link>
</Nav>
</Offcanvas.Body>
</Navbar.Offcanvas>
</Container>
</Navbar>
</>
);
