How to hide collapsible Bootstrap navbar on click

I've created this collapsable navbar using Bootstrap 4 that works nicely, but I would like it to close when the user clicks on a link. Any way to do this? Thanks

html navbar:

<nav class="navbar navbar-toggleable-md fixed-top">
			
<button id="nav-btn"class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarDiv"  aria-expanded="false" aria-label="Toggle navigation">
		<span class="icon-bar"></span>
		<span class="icon-bar"></span>
		<span class="icon-bar"></span>
 </button>
			
			<div class="container">
			  
				<a class="navbar-brand" href="#"><img src="Images/logo.png" width="60px"></a>

					<div class="collapse navbar-collapse" id="navbarDiv">
				  
						<ul class="navbar-nav mr-auto">
					
							<li class="nav-item active">
					  
								<a class="nav-link" href="#home">Home <span class="sr-only">(current)</span></a>
					  
				  			</li>
					
							<li class="nav-item">
					  
								<a class="nav-link" href="#about-us">About</a>
					  
							</li>
					
							<li class="nav-item">
					  
								<a class="nav-link" href="#pricing">Pricing</a>
					  
							</li>
					
						</ul>
		
					</div>
				
			</div>
			
		</nav>

css for .icon-bar, since Bootstrap 4 doesn't use the icon-bar class.

.navbar-toggler .icon-bar {
  margin: 7px;
  display: block;
  width: 22px;
  height: 1px;
  background-color: #cccccc;
  border-radius: 1px;
}

Update 2021 - Bootstrap 5 (beta)

Use javascript to add a click event listener on the menu items to close the Collapse navbar..

const navLinks = document.querySelectorAll('.nav-item')
const menuToggle = document.getElementById('navbarSupportedContent')
const bsCollapse = new bootstrap.Collapse(menuToggle)
navLinks.forEach((l) => {
    l.addEventListener('click', () => { bsCollapse.toggle() })
})

BS5 demo javascript method

Or, Use the data-bs-toggle and data-bs-target data attributes in the markup on each link to toggle the Collapse navbar...

<nav class="navbar navbar-expand-lg navbar-light bg-light">
    <div class="container">
        <a class="navbar-brand" href="#">Navbar</a>
        <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </button>
        <div class="collapse navbar-collapse" id="navbarSupportedContent">
            <ul class="navbar-nav me-auto">
                <li class="nav-item active">
                    <a class="nav-link" href="#" data-bs-toggle="collapse" data-bs-target=".navbar-collapse.show">Home</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#" data-bs-toggle="collapse" data-bs-target=".navbar-collapse.show">Link</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link disabled" href="#" data-bs-toggle="collapse" data-bs-target=".navbar-collapse.show">Disabled</a>
                </li>
            </ul>
            <form class="d-flex my-2 my-lg-0">
                <input class="form-control me-sm-2" type="search" placeholder="Search" aria-label="Search">
                <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
            </form>
        </div>
    </div>
</nav>

Update 2019 - Bootstrap 4

The navbar has changed, but the "close after click" method is still the same:

BS4 demo data-toggle method

Bootstrap 3 (original answer)

You can add the collapse component to the links like this..

<ul class="navbar-nav mr-auto">
     <li class="nav-item active">
         <a class="nav-link" href="#home" data-toggle="collapse" data-target=".navbar-collapse.show">Home <span class="sr-only">(current)</span></a>
     </li>
     <li class="nav-item">
         <a class="nav-link" href="#about-us" data-toggle="collapse" data-target=".navbar-collapse.show">About</a>
     </li>
     <li class="nav-item">
         <a class="nav-link" href="#pricing" data-toggle="collapse" data-target=".navbar-collapse.show">Pricing</a>
     </li>
 </ul>

BS3 demo using 'data-toggle' method

Or, (perhaps a better way) use jQuery like this..

$('.navbar-nav>li>a').on('click', function(){
    $('.navbar-collapse').collapse('hide');
});

BS3 demo using jQuery method

I am using ANGULAR and since it gave me problems the routerLink just add the data-toggle and target in the li tag.... or use jquery like "ZimSystem"

<div class="collapse navbar-collapse" id="navbarSupportedContent">
      <ul class="navbar-nav mr-auto">
        <li class="nav-item" data-toggle="collapse" data-target=".navbar-collapse.show">
          <a class="nav-link" routerLink="/inicio" routerLinkActive="active" >Inicio</a>
        </li>
      </ul>

You can call $.collapse('hide'); with an event handler on the links.

$('.nav-link').on('click',function() {
  $('.navbar-collapse').collapse('hide');
});

.navbar-toggler .icon-bar {
  margin: 7px;
  display: block;
  width: 22px;
  height: 1px;
  background-color: #cccccc;
  border-radius: 1px;
}

With trying out above solutions, I was missing a solution for Dropdown toggles, so here you go! Also opens submenu items.

Maybe you have to tweak it a bit if your toggle class is different.

$('.navbar-nav li a').on('click', function(){
    if(!$( this ).hasClass('dropdown-toggle')){
        $('.navbar-collapse').collapse('hide');
    }
});

this is the solution to close menu when click on anchor then apply this line in list item

     data-target="#sidenav-collapse-main" data-toggle="collapse"

the real example that work for me is below

      <li class="nav-item" data-target="#sidenav-collapse-main" data- 
      toggle="collapse" >
      <a class="nav-link" routerLinkActive="active" routerLink="/admin/users">
        <i class="ni ni-single-02  text-orange"></i> Users
      </a>
      </li>

The easiest way to do it using only Angular 2/4 template with no coding:

<nav class="navbar navbar-default" aria-expanded="false">
  <div class="container-wrapper">

    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" (click)="isCollapsed = !isCollapsed">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
    </div>

    <div class="navbar-collapse collapse no-transition" [attr.aria-expanded]="!isCollapsed" [ngClass]="{collapse: isCollapsed}">
      <ul class="nav navbar-nav" (click)="isCollapsed = !isCollapsed">
        <li [routerLinkActive]="['active']" [routerLinkActiveOptions]="{exact: true}"><a routerLink="/">Home</a></li>
        <li [routerLinkActive]="['active']"><a routerLink="/about">About</a></li>
        <li [routerLinkActive]="['active']"><a routerLink="/portfolio">Portfolio</a></li>
        <li [routerLinkActive]="['active']"><a routerLink="/contacts">Contacts</a></li>
      </ul>
    </div>

  </div>
</nav>

I am using Angular 5 with Boostrap 4. It works for me in this way.

 $(document).on('click', '.navbar-nav>li>a, .navbar-brand, .dropdown-menu>a', function (e) {
      if ( $(e.target).is('a') && $(e.target).attr('class') != 'nav-link dropdown-toggle' ) {
        $('.navbar-collapse').collapse('hide');
      }
    });
   }

<nav class="navbar navbar-expand-lg navbar-dark bg-primary">
  <a class="navbar-brand" [routerLink]="['/home']">FbShareTool</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarColor01" aria-controls="navbarColor01" aria-expanded="false" aria-label="Toggle navigation" style="">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse" id="navbarColor01">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active" *ngIf="_myAuthService.isAuthenticated()">
        <a class="nav-link" [routerLink]="['/dashboard']">Dashboard <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item dropdown" *ngIf="_myAuthService.isAuthenticated()">
          <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
            Manage
          </a>
          <div class="dropdown-menu" aria-labelledby="navbarDropdown">
            <a class="dropdown-item" [routerLink]="['/fbgroup']">Facebook Group</a>
            <div class="dropdown-divider"></div>
            <a class="dropdown-item" href="#">Fetch Data</a>
          </div>
      </li>
    </ul>

    <ul class="navbar-nav navbar-right navbar-right-link">
        <li class="nav-item" *ngIf="!_myAuthService.isAuthenticated()" >
            <a class="nav-link" (click)="logIn()">Login</a>
        </li>
        <li class="nav-item" *ngIf="_myAuthService.isAuthenticated()">
           <a class="nav-link">{{ _myAuthService.userDetails.displayName }}</a>
        </li>
        <li class="nav-item" *ngIf="_myAuthService.isAuthenticated() && _myAuthService.userDetails.photoURL">
            <a>
              <img [src]="_myAuthService.userDetails.photoURL" alt="profile-photo" class="img-fluid rounded" width="40px;">
            </a>
        </li>
        <li class="nav-item" *ngIf="_myAuthService.isAuthenticated()">
            <a class="nav-link" (click)="logOut()">Logout</a>
        </li>
    </ul>

  </div>
</nav>

This code simulates a click on the burguer button to close the navbar by clicking on a link in the menu, keeping the fade out effect. Solution with typescript for angular 7. Avoid routerLink problems.

ToggleNavBar () {
	let element: HTMLElement = document.getElementsByClassName( 'navbar-toggler' )[ 0 ] as HTMLElement;
	if ( element.getAttribute( 'aria-expanded' ) == 'true' ) {
		element.click();
	}
}

<li class="nav-item" [routerLinkActive]="['active']">
	<a class="nav-link" [routerLink]="['link1']" title="link1" (click)="ToggleNavBar()">link1</a>
</li>

In my case the menu was always in the shown state after using the bootstrap 5 js solution of Zim. The problem was resolved after adding toggle: false to the Collapse object constructor as also shown in one example of the specification.

Modified code of Zen:

const navLinks = document.querySelectorAll('.nav-item')
const menuToggle = document.getElementById('navbarSupportedContent')
const bsCollapse = new bootstrap.Collapse(menuToggle, {
  toggle: false
})
navLinks.forEach((l) => {
    l.addEventListener('click', () => { bsCollapse.toggle() })
})

(I could not comment, so I created a separate answer)

None of the answers above was helpful since I use React Bootstrap. In this case, I had to create a state which stored whether the navbar was collapsed or expanded.

The state gets updated whenever I toggle/click a link.

The toggle happens if I click the toggle menu itself.

The closure happens whenever I click a link.

Here is a code snippet that does the same:

function Navigation() {
	const [expanded, setExpanded] = useState(false);

	const navToggle = () => {
		setExpanded(expanded ? false : true);
	};

	const closeNav = () => {
		setExpanded(false);
	};

	return (
		<React.Fragment>
			<Navbar expand="lg" expanded={expanded}>
				<Container>
					<Navbar.Brand as={Link} to="/" onClick={closeNav}>
						Site Header
					</Navbar.Brand>
					<Navbar.Toggle aria-controls="basic-navbar-nav" onClick={navToggle} />
					<Navbar.Collapse id="basic-navbar-nav">
						<Nav className="me-auto">
							<Nav.Link to="/link1" onClick={closeNav}>
								Link 1
							</Nav.Link>
							<Nav.Link to="/link2" onClick={closeNav}>
								Link 2
							</Nav.Link>
							<Nav.Link to="/link3" onClick={closeNav}>
								Link 3
							</Nav.Link>
						</Nav>
					</Navbar.Collapse>
				</Container>
			</Navbar>
		</React.Fragment>
	);
}

I have modified the answer of Zim. Now the code closes the navbar only in case it is open.

const navLinks = document.querySelectorAll('.nav-item')
const menuToggle = document.getElementById('navbarSupportedContent')
const bsCollapse = new bootstrap.Collapse(menuToggle, {
  toggle: false
})
navLinks.forEach((l) => {
    l.addEventListener('click', () => {
        if(bsCollapse._isShown()){
            bsCollapse.hide()
        }
    })
})

You can use a simply bind on click and close, like this: (click)="drawer.close()

<a class="nav-link" [routerLink]="navItem.link" routerLinkActive="selected" (click)="drawer.close()">

add below code in your < a > TAG

data-toggle="collapse" data-target=".navbar-collapse.show"

as shows below in every TAG

<li class="nav-item">
   <a class="nav-link" href="#about-us" data-toggle="collapse" data-target=".navbar-collapse.show">About</a>
</li>

BOOTSTRAP 5

/* FOR MOBILE ONLY */
if (window.matchMedia("(max-width: 991px)").matches) {
  const navLinks = document.querySelectorAll('.nav- 
  item:not(.dropdown)');
  const menuToggle = document.getElementById('navbarToggler');
  const bsCollapse = new bootstrap.Collapse(menuToggle, {toggle: false});
  navLinks.forEach((l) => {
    l.addEventListener('click', () => { bsCollapse.toggle() })
  });
}

Set your breakpoint (991 for "navbar-expand-lg")

In your HTML: set the ID, data-bs-target...

Work nice for me
