Nav Menu Active Element and State Management Issue

I am trying to show an active <Nav.Link> element for the current page, but it keeps getting reset when I go between pages to the default value. Each of the links goes to a different route I have defined in React-Router. I am trying to use jotai for state management to store the value of the current page, but am not able to get the correct value to display.
For example, the code below has pills to show the active selection in the nav. I want to be able to do this even when I go to a different page since this is the nav menu.
import Nav from 'react-bootstrap/Nav';
function TabsExample() {
return (
<Nav variant="pills" defaultActiveKey="/home">
<Nav.Item>
<Nav.Link href="/home">Active</Nav.Link>
</Nav.Item>
<Nav.Item>
<Nav.Link eventKey="link-1">Option 2</Nav.Link>
</Nav.Item>
<Nav.Item>
<Nav.Link eventKey="disabled" disabled>
Disabled
</Nav.Link>
</Nav.Item>
</Nav>
);
}
export default TabsExample;
However, I believe my page keeps re-rendering/reloading (goes white for a brief second) for some reason whenever I go to a different page.
There might be something I'm not getting, so please let me know.

The issue here is likely that the Nav.Link component renders an anchor <a> element by default and this is causing the page to reload when you click the links. You can specify each Nav.Link to render the NavLink (or Link) component exported from react-router-dom so that clicking links will now correctly be handled by RRD. Specify a to prop instead of an href prop, and set the eventKey prop to match the link target so the "pill" state can work as well.
Example:
import { NavLink } from "react-router-dom";
import "bootstrap/dist/css/bootstrap.min.css";
import Nav from "react-bootstrap/Nav";
function PillsExample() {
return (
<Nav variant="pills">
<Nav.Item>
<Nav.Link as={NavLink} end to="/" eventKey="/"> // * Note on end prop
Home
</Nav.Link>
</Nav.Item>
<Nav.Item>
<Nav.Link as={NavLink} to="/foo" eventKey="/foo">
Foo
</Nav.Link>
</Nav.Item>
<Nav.Item>
<Nav.Link as={NavLink} to="/bar" eventKey="/bar">
Bar
</Nav.Link>
</Nav.Item>
</Nav>
);
}
* Note: If the end prop is used, it will ensure this component isn't matched as "active" when its descendant paths are matched. See NavLink for more component details.

Menu does not collapse when you click on one of the menu items on Mobile Devices

Hi All i need some help :)
I working on a Gatsby, React portfolio where i have a problem with The Menu It does not collapse when you click on one of the menu items on Mobile Devices.
The menu is working fine on desktop.
The menu works fine on all devices until I installed the react-scroll package and set it up.
I have tried to search on Google for help and i found some simlare issues but i still dont know to fix the problem. :)
Hope you can help.
There is to Nav components i my project:
This my Project on SandBox:
NavBar.js
https://codesandbox.io/s/gatsby-starter-and-portfolio-jr9tn?file=/src/components/Navbar/Navbar.js
NavbarLinks:
https://codesandbox.io/s/gatsby-starter-and-portfolio-jr9tn?file=/src/components/Navbar/NavbarLinks.js

Here you have your CodeSandbox fixed: https://codesandbox.io/s/gatsby-starter-and-portfolio-forked-43thz?file=/src/components/Navbar/NavbarLinks.js
What was happening is that, since you've installed react-scroll, the state was never updated when an item was selected so, React's rehydration was never occurring and your menu was never closed. The code is a bit redundant however I've managed to get it to work. What I've added is a simple function passed via props that toggle the menu.
In your NavBar.js, instead of:
<Toggle
navbarOpen={navbarOpen}
onClick={() => setNavbarOpen(!navbarOpen)}
>
If added a function, since it's not a good practice to trigger effects directly bonded in the components. I've changed it to:
<Toggle navbarOpen={navbarOpen} onClick={toggleMenu}>
That toggleMenu function, is a simply function that does the same than your previous one:
const toggleMenu = () => setNavbarOpen(!navbarOpen)
Now, you have isolated that piece of functionality and you can reuse it, passing it to your child component (NavbarLinks):
{navbarOpen ? (
<Navbox>
<NavbarLinks toggleMenu={toggleMenu} />
</Navbox>
) : (
<Navbox open>
<NavbarLinks toggleMenu={toggleMenu} />
</Navbox>
)}
Note: this code is redundant, should be refactored to avoid that kind of unnecessary repetition. For example, something like this is much better:
<Navbox open={navbarOpen}>
<NavbarLinks toggleMenu={toggleMenu} />
</Navbox>
As you can see, you <NavbarLinks> have the functionality to toggle the menu in toggleMenu function so there you can trigger the function in every click (onClick):
const NavbarLinks = ({ toggleMenu })=> {
return (
<>
<NavItem
activeClass="active"
to="section1"
spy={true}
smooth={true}
duration={1000}
onClick={toggleMenu}
>
About
</NavItem>
<NavItem
activeClass="active"
to="section2"
spy={true}
smooth={true}
duration={1000}
onClick={toggleMenu}
>
Test
</NavItem>
<NavItem
activeClass="active"
to="section3"
spy={true}
smooth={true}
duration={1000}
onClick={toggleMenu)}
>
Gallery
</NavItem>
<NavItem to="/page-2">Contact</NavItem>
</>
)
}
Since you are destructuring props, you have the toggleMenu function available directly.

Warning: validateDOMNesting(...): <a> cannot appear as a descendant of <a>

I'm trying to use react-router with reactstrap with create-react-app.
In the routing page, I needed to use state for the reactstrap, so I converted the router from a variable to a class, but I get this warning:
Warning: validateDOMNesting(...): <a> cannot appear as a descendant of <a>.
I don't know what to do. I needed to style the router navigation using reactstrap, so I did this:
<NavLink
componentClass={Link}
href="/contact"
to="/contact"
active={location.pathname === '/contact'}
>
anywords
</NavLink>
<Navbar dark id="RouterNavbar" expand="md">
<NavbarBrand id="NavBrand"href="#x">
<ul>
{/* a bunch of <li></li> */}
</ul>
</NavbarBrand>
<NavbarToggler id="NavBarToggler" onClick={this.toggle1.bind(this)} />
<Collapse isOpen={this.state.isOpen1} navbar>
<Nav className="ml-auto" navbar>
<NavItem>
<NavLink href="#x"><Link id="RouterNavLink" style={None} to="/contact">anywords</Link></NavLink>
</NavItem>
{/* just more of the above */}
Other than a couple of <li> coming close to each other at random times, hot reloading not working sometimes, and the warning message I get in the console, nothing bad happens, but when I read about this issue, I found out that I shouldn't do this.

This is the code which causing the error,
<NavLink href="#x"><Link id="RouterNavLink" style={None} to="/contact">anywords</Link></NavLink>
Which is converted to,
<a><a></a></a>
So you are getting error,
Warning: validateDOMNesting(…): <a> cannot appear as a descendant of <a>
To solve this just use one of the follow,
<NavLink id="RouterNavLink" style={None} to="/contact">anywords</NavLink>
OR,
<Link id="RouterNavLink" style={None} to="/contact">anywords</Link>

Add the as prop (formerly componentClass) to your original NavLink to keep the styling while also silencing the warning.
See react-bootstrap#nav-link-props docs
Or View Screenshot
Original:
<NavLink href="#x">
<Link id="RouterNavLink" style={None} to="/contact">anywords</Link>
</NavLink>
New:
<Nav.Link as={Link} to="/contact">anywords</Nav.Link>

I would like to suggest an alternate solution which not only solve your problem but give you desired result. In any case someone else stumbled on this post like I did.
Use Link jsx element offered by react router dom but add className="nav-link" to it. This will give you styling of the NavLink jsx which react strap is using.
So, it should look like this,
<Link className="nav-link" id="RouterNavLink" style={None} to="/contact">anywords</Link>

you can try this in order to avoid the error
<NavItem as="li"> <Link>.....

I had same problem. It is because we can not use link, or a tag inside another like...
<a><a></a></a>
I wanted to apply className to my a tag in navigation bar. so i applied className to a tag in component and import that component in navigation bar component
<a className="nav-link" onClick={() => loginWithRedirect()}>
Login
</a>
This is how i use this link in navigation template,without any classname
<LoginButton />

React-Bootstrap - How to keep Navbar.Toggle button visible at all times?

I'm using React-Bootstrap to make a navigation menu. The toggle button once expanded contains my nav items to go to different parts of my app. So far I know it is supposed to be responsive to small-screened devices as the nav items disappear inside the toggle button as soon as the display width is smaller than 768px and appear inside the navbar if the screen is any wider.
What I want is to keep the toggle button, its behavior and its nav items (from the Navbar.Collapse) inside at all times. I've searched the documentation and other questions but haven't found any way to do this.
Here is my code :
import React from 'react';
import { bindActionCreators } from 'redux';
import { connect } from 'react-redux';
import { Glyphicon, Nav, Navbar, NavItem } from 'react-bootstrap';
import { actionCreators } from '../store/ExpeditionStore';
import './NavMenu.css';
const translations = require('../Translations');
class NavMenu extends React.Component {
render() {
return (
<Navbar inverse fixedTop fluid collapseOnSelect>
<Navbar.Header>
<Navbar.Toggle />
<Navbar.Brand>
{this.props.title}
</Navbar.Brand>
</Navbar.Header>
<Navbar.Collapse>
<Nav>
<NavItem>
<Glyphicon glyph='plane' />{translations.getCaption('shipment')}
</NavItem>
</Nav>
<Nav>
<NavItem onClick={() => this.props.switchLanguage(translations)}>
EN/FR
</NavItem>
</Nav>
</Navbar.Collapse>
</Navbar>
);
}
}
export default connect(
state => state.expeditionStore,
dispatch => bindActionCreators(actionCreators, dispatch)
)(NavMenu);
How to keep my toggle button and the Navbar.Collapse nav items inside it even if the device is wider than 768px?

Add expand attribute with value of "xl" or "xxl" to main Navbar tag. eg: expand="xxl"

Instead of using React-bootstrap approach, I suggest using normal bootstrap to achieve this result.
Put Bootstrap CDN link in your index.html file. Then this normal JSX code works for me:
<nav className="navbar narbar-expand-xl"> </nav>
Because the Bootstrap class narbar-expand-xl indicates that when screen equal or lower than the desktop size, the navbar will will collapse.
