Basic Example

Here's a complete navbar example with branding, navigation, collapse support and search functionality:

            
            <Navbar.Root expandOnBreakpoint="lg" class="bg-body-tertiary">
  <Container isFluid={true}>
    <Navbar.Brand href="#!">Navbar</Navbar.Brand>
    <Navbar.Toggler ariaLabel="Toggle navigation">
      <Navbar.TogglerIcon />
    </Navbar.Toggler>
    <Navbar.Collapse id="navbarSupportedContent">
      <Navbar.Nav class="me-auto mb-2 mb-lg-0">
        <Nav.Item>
          <Nav.Link isActive={true} href="#!">Home</Nav.Link>
        </Nav.Item>
        <Nav.Item>
          <Nav.Link href="#!">Link</Nav.Link>
        </Nav.Item>
        <Nav.Item>
          <Nav.Link isDisabled={true} href="#!">Disabled</Nav.Link>
        </Nav.Item>
      </Navbar.Nav>
      <form class="d-flex" role="search">
        <input class="form-control me-2" type="search" name="search" placeholder="Search" aria-label="Search" />
        <button class="btn btn-outline-success" type="submit">Search</button>
      </form>
    </Navbar.Collapse>
  </Container>
</Navbar.Root>

Color Schemes

Navbars can use various color schemes by combining Bootstrap background utilities with data-bs-theme attributes. You can use the new colorVariant prop to automatically apply the correct background color and text contrast.

The colorVariant prop supports all Bootstrap background color variants and automatically sets the appropriate data-bs-theme attribute based on the background color to ensure proper text contrast as per Bootstrap documentation.

            
            <!-- Dark theme navbar (dark background with light text) -->
<Navbar.Root expandOnBreakpoint="lg" class="bg-dark" data-bs-theme="dark">
  <Container isFluid={true}>
    <Navbar.Brand href="#!">Dark Navbar</Navbar.Brand>
    <Navbar.Toggler ariaLabel="Toggle navigation">
      <Navbar.TogglerIcon />
    </Navbar.Toggler>
    <Navbar.Collapse id="navbarDarkContent">
      <Navbar.Nav class="me-auto mb-2 mb-lg-0">
        <Nav.Item>
          <Nav.Link isActive={true} href="#!">Home</Nav.Link>
        </Nav.Item>
        <Nav.Item>
          <Nav.Link href="#!">Link</Nav.Link>
        </Nav.Item>
      </Navbar.Nav>
    </Navbar.Collapse>
  </Container>
</Navbar.Root>

<!-- Primary color navbar using class and data-bs-theme (legacy approach) -->
<Navbar.Root expandOnBreakpoint="lg" class="bg-primary" data-bs-theme="dark">
  <Container isFluid={true}>
    <Navbar.Brand href="#!">Primary Navbar</Navbar.Brand>
    <Navbar.Toggler ariaLabel="Toggle navigation">
      <Navbar.TogglerIcon />
    </Navbar.Toggler>
  </Container>
</Navbar.Root>

<!-- Primary color navbar using variant (recommended approach) -->
<Navbar.Root expandOnBreakpoint="lg" colorVariant="primary">
  <Container isFluid={true}>
    <Navbar.Brand href="#!">Primary Navbar with Variant</Navbar.Brand>
    <Navbar.Toggler ariaLabel="Toggle navigation">
      <Navbar.TogglerIcon />
    </Navbar.Toggler>
  </Container>
</Navbar.Root>

Containers

Navbars can use various container options to control their horizontal width. Choose from a responsive fixed-width container (default) or a fluid-width container (full width).

Default container (responsive fixed width):
Fluid container (full width):
No container: 
            
            <!-- Default container (responsive fixed width) -->
<Navbar.Root expandOnBreakpoint="lg" class="bg-body-tertiary">
  <Container>
    <Navbar.Brand href="#!">Default Container</Navbar.Brand>
    <Navbar.Toggler ariaLabel="Toggle navigation">
      <Navbar.TogglerIcon />
    </Navbar.Toggler>
  </Container>
</Navbar.Root>

<!-- Fluid container (full width) -->
<Navbar.Root expandOnBreakpoint="lg" class="bg-body-tertiary">
  <Container isFluid={true}>
    <Navbar.Brand href="#!">Fluid Container</Navbar.Brand>
    <Navbar.Toggler ariaLabel="Toggle navigation">
      <Navbar.TogglerIcon />
    </Navbar.Toggler>
  </Container>
</Navbar.Root>

<!-- No container -->
<Navbar.Root expandOnBreakpoint="lg" class="bg-body-tertiary">
  <Navbar.Brand href="#!" class="ms-3">No Container</Navbar.Brand>
  <Navbar.Toggler ariaLabel="Toggle navigation" class="me-3">
    <Navbar.TogglerIcon />
  </Navbar.Toggler>
</Navbar.Root>

Placement

Use the placement property to position navbars in different locations within your page.

The following placement options are available:

  • fixed-top - Fixes the navbar at the top of the viewport
  • fixed-bottom - Fixes the navbar at the bottom of the viewport
  • sticky-top - Makes the navbar stick to the top when scrolling past it
  • sticky-bottom - Makes the navbar stick to the bottom when scrolling past it
These examples are not rendered here to avoid interfering with the page layout.
            
            <!-- Fixed top navbar -->
<Navbar.Root expandOnBreakpoint="lg" class="bg-body-tertiary" placement="fixed-top">
  <Container isFluid={true}>
    <Navbar.Brand href="#!">Fixed Top</Navbar.Brand>
    <Navbar.Toggler ariaLabel="Toggle navigation">
      <Navbar.TogglerIcon />
    </Navbar.Toggler>
  </Container>
</Navbar.Root>

<!-- Fixed bottom navbar -->
<Navbar.Root expandOnBreakpoint="lg" class="bg-body-tertiary" placement="fixed-bottom">
  <Container isFluid={true}>
    <Navbar.Brand href="#!">Fixed Bottom</Navbar.Brand>
    <Navbar.Toggler ariaLabel="Toggle navigation">
      <Navbar.TogglerIcon />
    </Navbar.Toggler>
  </Container>
</Navbar.Root>

<!-- Sticky top navbar -->
<Navbar.Root expandOnBreakpoint="lg" class="bg-body-tertiary" placement="sticky-top">
  <Container isFluid={true}>
    <Navbar.Brand href="#!">Sticky Top</Navbar.Brand>
    <Navbar.Toggler ariaLabel="Toggle navigation">
      <Navbar.TogglerIcon />
    </Navbar.Toggler>
  </Container>
</Navbar.Root>

Scrolling

Add isVerticalScrolling=true to a Navbar.Nav component to enable vertical scrolling within the toggleable contents of a collapsed navbar.

            
            <Navbar.Root expandOnBreakpoint="lg" class="bg-body-tertiary">
  <Container isFluid={true}>
    <Navbar.Brand href="#!">Navbar Scroll</Navbar.Brand>
    <Navbar.Toggler ariaLabel="Toggle navigation">
      <Navbar.TogglerIcon />
    </Navbar.Toggler>
    <Navbar.Collapse id="navbarScroll">
      <Navbar.Nav class="me-auto mb-2 mb-lg-0" isVerticalScrolling={true} style="--bs-scroll-height: 100px;">
        <Nav.Item>
          <Nav.Link isActive={true} href="#!">Home</Nav.Link>
        </Nav.Item>
        <Nav.Item>
          <Nav.Link href="#!">Link 1</Nav.Link>
        </Nav.Item>
        <Nav.Item>
          <Nav.Link href="#!">Link 2</Nav.Link>
        </Nav.Item>
        <Nav.Item>
          <Nav.Link href="#!">Link 3</Nav.Link>
        </Nav.Item>
        <Nav.Item>
          <Nav.Link href="#!">Link 4</Nav.Link>
        </Nav.Item>
        <Nav.Item>
          <Nav.Link href="#!">Link 5</Nav.Link>
        </Nav.Item>
        <Nav.Item>
          <Nav.Link href="#!">Link 6</Nav.Link>
        </Nav.Item>
      </Navbar.Nav>
    </Navbar.Collapse>
  </Container>
</Navbar.Root>

Text

Add non-navigational text to your navbar with Navbar.Text component.

            
            <Navbar.Root expandOnBreakpoint="lg" class="bg-body-tertiary">
  <Container isFluid={true}>
    <Navbar.Brand href="#!">Navbar</Navbar.Brand>
    <Navbar.Text>
      Navbar text with an inline element
    </Navbar.Text>
    <Navbar.Toggler ariaLabel="Toggle navigation">
      <Navbar.TogglerIcon />
    </Navbar.Toggler>
    <Navbar.Collapse id="navbarText">
      <Navbar.Nav class="me-auto mb-2 mb-lg-0">
        <Nav.Item>
          <Nav.Link isActive={true} href="#!">Home</Nav.Link>
        </Nav.Item>
        <Nav.Item>
          <Nav.Link href="#!">Features</Nav.Link>
        </Nav.Item>
        <Nav.Item>
          <Nav.Link href="#!">Pricing</Nav.Link>
        </Nav.Item>
      </Navbar.Nav>
      <Navbar.Text>
        Signed in as: <a href="#!">Mark Otto</a>
      </Navbar.Text>
    </Navbar.Collapse>
  </Container>
</Navbar.Root>

Variant

Use the colorVariant prop to apply predefined color themes to your navbar. This prop automatically handles the theme attributes for you.

            
            <!-- Using variant prop for automatic theme handling -->
<Navbar.Root expandOnBreakpoint="lg" colorVariant="primary">
  <Container isFluid={true}>
    <Navbar.Brand href="#!">Primary Navbar</Navbar.Brand>
    <Navbar.Toggler ariaLabel="Toggle navigation">
      <Navbar.TogglerIcon />
    </Navbar.Toggler>
    <Navbar.Collapse id="navbarVariantContent">
      <Navbar.Nav class="me-auto mb-2 mb-lg-0">
        <Nav.Item>
          <Nav.Link isActive={true} href="#!">Home</Nav.Link>
        </Nav.Item>
        <Nav.Item>
          <Nav.Link href="#!">Link</Nav.Link>
        </Nav.Item>
      </Navbar.Nav>
    </Navbar.Collapse>
  </Container>
</Navbar.Root>

<!-- Using variant prop with other colors -->
<Navbar.Root expandOnBreakpoint="lg" colorVariant="success">
  <Container isFluid={true}>
    <Navbar.Brand href="#!">Success Navbar</Navbar.Brand>
    <Navbar.Toggler ariaLabel="Toggle navigation">
      <Navbar.TogglerIcon />
    </Navbar.Toggler>
  </Container>
</Navbar.Root>

<!-- Light colored navbar with variant -->
<Navbar.Root expandOnBreakpoint="lg" colorVariant="light">
  <Container isFluid={true}>
    <Navbar.Brand href="#!">Light Navbar</Navbar.Brand>
    <Navbar.Toggler ariaLabel="Toggle navigation">
      <Navbar.TogglerIcon />
    </Navbar.Toggler>
  </Container>
</Navbar.Root>

Offcanvas

Transform your navbar with an offcanvas component that displays navigation content when the navbar is collapsed or expanded.

Navbar.Toggler automatically receives aria-controls while the nested Offcanvas.Root is rendered, including when the panel uses a generated ID. The association follows ID changes and is removed when the panel leaves the DOM after closing. When multiple controlled panels are rendered, their IDs are listed together. An explicit aria-controls on the toggler takes precedence.

Responsive Behavior: The offcanvas content will automatically show when the navbar expands at the XL breakpoint, creating a seamless responsive navigation experience.
            
            <Navbar.Root expandOnBreakpoint="xl" class="bg-body-tertiary">
    <Container isFluid={true}>
        <Navbar.Brand href="#!">Navbar</Navbar.Brand>
        <Navbar.Toggler ariaLabel="Toggle navigation">
            <Navbar.TogglerIcon />
        </Navbar.Toggler>
        <Offcanvas.Root placement="end" useBackdrop={true}>
            <Offcanvas.Header isDismissible={true}>
                <Offcanvas.Title>Offcanvas in a Navbar</Offcanvas.Title>
            </Offcanvas.Header>
            <Offcanvas.Body>
                <Navbar.Nav class="justify-content-end flex-grow-1 pe-3">
                    <Nav.Item>
                        <Nav.Link isActive={true} href="#!">Home</Nav.Link>
                    </Nav.Item>
                    <Nav.Item>
                        <Nav.Link href="#!">Link</Nav.Link>
                    </Nav.Item>
                </Navbar.Nav>
                <form class="d-flex mt-3" role="search">
                    <input class="form-control me-2" type="search" name="search" placeholder="Search" aria-label="Search" />
                    <button class="btn btn-outline-success" type="submit">Search</button>
                </form>
            </Offcanvas.Body>
        </Offcanvas.Root>
    </Container>

CSS Classes

The component applies Bootstrap's navbar classes based on the provided props:

  • navbar - Base class for the Navbar component
  • navbar-expand - Always inline when the breakpoint is omitted or xs
  • navbar-expand-* - Applied for named responsive breakpoints; neither expansion class is used for false
  • navbar-brand - Applied to Navbar.Brand components
  • navbar-nav - Applied to Navbar.Nav components
  • navbar-text - Applied to Navbar.Text components
  • navbar-toggler - Applied to Navbar.Toggler components
  • navbar-toggler-icon - Applied to Navbar.TogglerIcon components
  • navbar-collapse - Applied to Navbar.Collapse components
  • collapse - Applied to Navbar.Collapse components
  • navbar-scrolling - Applied when isVerticalScrolling=true on Navbar.Nav

Responsive Behavior

Choose an expansion breakpoint to make navigation collapse on smaller screens:

  • Use expandOnBreakpoint={false} to keep navigation collapsible at every width, or to render a plain wrapping navbar without responsive expansion classes.
  • At smaller screen sizes (below the specified breakpoint), the navbar collapses and requires the toggler button to expand.
  • At larger screen sizes (at or above the specified breakpoint), the navbar content displays horizontally.
  • Use expandOnBreakpoint="lg", for example, to collapse below 992px. The breakpoint can change without remounting.
  • Omitting the prop or choosing xs keeps navigation expanded at every width, using Bootstrap's navbar-expand class.
  • An inheriting Offcanvas follows the same breakpoint. In inline mode it has no backdrop or body-scroll lock, including on phones with xs.
  • A menu opened with the toggler resets after entering inline mode. Explicit Offcanvas isShown assignments survive responsive changes until a later toggle, dismissal, or changed prop replaces them. An unchanged prop is not reapplied; to reopen after dismissal, change isShown to false and then true.
