Supported content

c-navbar comes with built-in support for a handful of sub-components. Choose from the following as needed:

• cNavbarBrand for your company, product, or project name.
• c-navbar-nav for a full-height and lightweight navigation (including support for dropdowns).
• c-navbar-toggler for use with our collapse plugin and other navigation toggling behaviors.
• Flex and spacing utilities for any form controls and actions.
• c-navbar-text for adding vertically centered strings of text.
• cCollapse for grouping and hiding navbar contents by a parent breakpoint.

Examples

Basic usage

Here's an example of all the sub-components included in a responsive light-themed navbar that automatically collapses at thelg (large) breakpoint.

Brand

ThecNavbarBrand can be applied to most elements, but an anchor works best, as some elements might require utility classes or custom styles.

AddingcNavbarBrand to the images will likely always require custom styles or utilities to properly size. Here are some examples to demonstrate.

Nav

c-navbar navigation is based on `c-navbar-nav. Navigation in navbars will also grow to occupy as much horizontal space as possible to keep your navbar contents securely aligned.

You can avoid the list-based approach entirely if you prefere.

You can also use dropdowns in your navbar. Please note thatc-dropdown component requiresvariant="nav-item".

Forms

Place various form controls and components within a navbar:

Immediate child elements ofc-navbar use flex layout and will default tojustify-content: space-between. Use additional flex utilities as needed to adjust this behavior.

Input groups work, too. If your navbar is an entire form, or mostly a form, you can use thecForm element as thecContainer and save some HTML.

Various buttons are supported as part of these navbar forms, too. This is also a great reminder that vertical alignment utilities can be used to align different sized elements.

Text

Navbars may contain bits of text with the help ofc-navbar-text. It adjusts vertical alignment and horizontal spacing for strings of text.

Mix and match with other components and utilities as needed.

Color schemes

Theming the navbar has never been easier thanks to the combination of theming classes andbackground-color utilities. SetcolorScheme="light" for use with light background colors, orcolorScheme="dark" for dark background colors. Then, customize with.bg-* utilities.

Containers

Although it's not required, you can wrap ac-navbar in ac-container to center it on a page–though. Note that an inner container is still needed. Or you can add a container inside thec-navbar to only center the contents of a fixed or static top navbar.

Use any of the responsive containers to change how wide the content in your navbar is presented.

Placement

Use ourplacement properly to place navbars in non-static positions. Choose from fixed to the top, fixed to the bottom, or stickied to the top (scrolls with the page until it reaches the top, then stays there). Fixed navbars useposition: fixed, meaning they're pulled from the normal flow of the DOM and may require custom CSS (e.g.,padding-top on thebody) to prevent overlap with other elements.

Also note that.sticky-top usesposition: sticky, whichisn't fully supported in every browser.

Scrolling

Addscroll prop to ac-navbar-nav to enable vertical scrolling within the toggleable contents of a collapsed navbar.By default, scrolling kicks in at75vh (75% of the viewport height), but you can override that with the local CSS custom property--cui-navbar-height or custom styles.At larger viewports when the navbar is expanded, content will appear as it does in a default navbar.

Please note that this behavior comes with a potential drawback ofoverflow — when settingoverflow-y: auto (required to scroll the content here),overflow-x is the equivalent ofauto, which will crop some horizontal content.

The example navbar usesscroll with, with some extra margin utilities for optimum spacing.

Responsive behavior

Navbars can usecNavbarToggler,cCollapse, andexpand="sm|md|lg|xl|xxl" property to determine when their content collapses behind a button. In combination with other utilities, you can easily choose when to show or hide particular elements.

For navbars that never collapse, add theexpand boolean property on thec-navbar. For navbars that always collapse, don't add any property.

Toggler

Navbar togglers are left-aligned by default, but should they follow a sibling element like acNavbarBrand, they'll automatically be aligned to the far right. Reversing your markup will reverse the placement of the toggler. Below are examples of different toggle styles.

External content

Sometimes you want to use the collapse plugin to trigger a container element for content that structurally sits outside of thec-navbar.

Do not forget about users of assistive technologies. In this case you should move the focus programmatically to the opened container. Make sure that the toggler has also thearia-controls attribute, pointing to theid of the content container.

Offcanvas

Transform your expanding and collapsing navbar into anoffcanvas drawer. You can extend both the offcanvas default styles and use ourexpand="*" prop to create a custom navigation sidebar.

In the example below, to create an offcanvas navbar that is always collapsed across all breakpoints, omit theexpand="*" prop entirely.

To create an offcanvas navbar that expands into a normal navbar at a specific breakpoint likexl, useexpand="xl" property.

Customizing

CSS variables

Angular navbar uses local CSS variables on.navbar for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.

Some additional CSS variables are also present on.navbar-nav:
