The component <b-navbar>
is a wrapper that positions branding, navigation, and other elements
into a concise header. It's easily extensible and thanks to the <b-collapse>
component, it can
easily integrate responsive behaviors.
Example:
<div>
<b-navbar toggleable="lg" type="dark" variant="info">
<b-navbar-brand href="#">NavBar</b-navbar-brand>
<b-navbar-toggle target="nav-collapse"></b-navbar-toggle>
<b-collapse id="nav-collapse" is-nav>
<b-navbar-nav>
<b-nav-item href="#">Link</b-nav-item>
<b-nav-item href="#" disabled>Disabled</b-nav-item>
</b-navbar-nav>
<!-- Right aligned nav items -->
<b-navbar-nav class="ml-auto">
<b-nav-form>
<b-form-input size="sm" class="mr-sm-2" placeholder="Search"></b-form-input>
<b-button size="sm" class="my-2 my-sm-0" type="submit">Search</b-button>
</b-nav-form>
<b-nav-item-dropdown text="Lang" right>
<b-dropdown-item href="#">EN</b-dropdown-item>
<b-dropdown-item href="#">ES</b-dropdown-item>
<b-dropdown-item href="#">RU</b-dropdown-item>
<b-dropdown-item href="#">FA</b-dropdown-item>
</b-nav-item-dropdown>
<b-nav-item-dropdown right>
<!-- Using 'button-content' slot -->
<template slot="button-content"><em>User</em></template>
<b-dropdown-item href="#">Profile</b-dropdown-item>
<b-dropdown-item href="#">Sign Out</b-dropdown-item>
</b-nav-item-dropdown>
</b-navbar-nav>
</b-collapse>
</b-navbar>
</div>
<!-- b-navbar.vue -->
<b-navbar>
supports the standard Bootstrap v4 available background color variants. Set the
variant
prop to one of the following values to change the background color: primary
, success
,
info
, warning
, danger
, dark
, or light
.
Control the text color by setting type
prop to light
for use with light background color
variants, or dark
for dark background color variants.
Control the placement of the navbar by setting one of two props:
prop | type | default | description |
---|---|---|---|
fixed |
String | null |
Set to top for fixed to the top of the viewport, or bottom for fixed to the bottom of the viewport. |
sticky |
Boolean | false |
Set to true to make the navbar stick to the top of the viewport (or parent container that has position: relative set) when scrolled. |
Notes:
position: fixed
. You may need to adjust your document top/bottom
padding or margin.position: sticky
(used for sticky
) is not fully supported in every browser. For browsers
that do not support position: sticky
, it will fallback natively to position: relative
.Navbars come with built-in support for a handful of sub-components. Choose from the following as needed:
<b-navbar-brand>
for your company, product, or project name.<b-navbar-nav>
for a full-height and lightweight navigation (including support for dropdowns).<b-nav-item>
for link (and router-link) action items<b-nav-item-dropdown>
for navbar dropdown menus<b-nav-text>
for adding vertically centered strings of text.<b-nav-form>
for any form controls and actions.<b-navbar-toggle>
for use with the <b-collapse is-nav>
component.<b-collapse is-nav>
for grouping and hiding navbar contents by a parent breakpoint.<b-navbar-brand>
The <b-navbar-brand>
generates a link if href
is provided, or a <router-link>
if to
is
provided. If neither is given it renders as a <div>
tag. You can override the tag type by setting
the tag
prop to the element you would like rendered:
<div>
<!-- As a link -->
<b-navbar variant="faded" type="light">
<b-navbar-brand href="#">BootstrapVue</b-navbar-brand>
</b-navbar>
</div>
<!-- b-navbar-brand-link.vue -->
<div>
<!-- As a heading -->
<b-navbar variant="faded" type="light">
<b-navbar-brand tag="h1" class="mb-0">BootstrapVue</b-navbar-brand>
</b-navbar>
</div>
<!-- b-navbar-brand-heading.vue -->
Adding images to the <b-navbar-brand>
will likely always require custom styles or utilities to
properly size. Here are some examples to demonstrate:
<div>
<!-- Just an image -->
<b-navbar variant="faded" type="light">
<b-navbar-brand href="#">
<img src="https://placekitten.com/g/30/30" alt="Kitten">
</b-navbar-brand>
</b-navbar>
</div>
<!-- b-navbar-brand-image.vue -->
<div>
<!-- Image and text -->
<b-navbar variant="faded" type="light">
<b-navbar-brand href="#">
<img src="https://placekitten.com/g/30/30" class="d-inline-block align-top" alt="Kitten">
BootstrapVue
</b-navbar-brand>
</b-navbar>
</div>
<!-- b-navbar-brand-image-and-text.vue -->
<b-navbar-nav>
Navbar navigation links build on the <b-navbar-nav>
parent component and requires the use of
<b-collapse is-nav>
and <b-nav-toggle>
toggler for proper responsive styling. Navigation in
navbars will also grow to occupy as much horizontal space as possible to keep your navbar contents
securely aligned.
<b-navbar-nav>
supports the following components:
<b-nav-item>
for link (and router-link) action items<b-nav-text>
for adding vertically centered strings of text.<b-nav-item-dropdown>
for navbar dropdown menus<b-nav-form>
for adding simple forms to the navbar.Note: The use of <b-nav is-nav-bar>
inside a <b-navbar>
has been deprecated. Use component
<b-navbar-nav>
instead.
<b-nav-item>
<b-nav-item>
is the primary link (and <router-link>
) component. Providing a to
prop value will
generate a <router-link>
while providing an href
prop value will generate a standard link.
Set the <b-nav-item>
active
prop will highlight the item as being the active page, Disable a
<b-nav-item>
by setting the prop disabled
to true.
Handle click events by specifying a handler for the @click
event on <b-nav-item>
.
<b-nav-text>
Navbars may contain bits of text with the help of <b-nav-text>
. This component adjusts vertical
alignment and horizontal spacing for strings of text.
<div>
<b-navbar toggleable="sm" type="light" variant="light">
<b-navbar-toggle target="nav-text-collapse"></b-navbar-toggle>
<b-navbar-brand>BootstrapVue</b-navbar-brand>
<b-collapse id="nav-text-collapse" is-nav>
<b-navbar-nav>
<b-nav-text>Navbar text</b-nav-text>
</b-navbar-nav>
</b-collapse>
</b-navbar>
</div>
<!-- b-navbar-text.vue -->
<b-nav-item-dropdown>
For <b-nav-item-dropdown>
usage, see the <b-dropdown>
docs. Note
split dropdowns are not supported in <b-navbar>
and <b-navbar-nav>
.
<div>
<b-navbar type="dark" variant="dark">
<b-navbar-nav>
<b-nav-item href="#">Home</b-nav-item>
<!-- Navbar dropdowns -->
<b-nav-item-dropdown text="Lang" right>
<b-dropdown-item href="#">EN</b-dropdown-item>
<b-dropdown-item href="#">ES</b-dropdown-item>
<b-dropdown-item href="#">RU</b-dropdown-item>
<b-dropdown-item href="#">FA</b-dropdown-item>
</b-nav-item-dropdown>
<b-nav-item-dropdown text="User" right>
<b-dropdown-item href="#">Account</b-dropdown-item>
<b-dropdown-item href="#">Settings</b-dropdown-item>
</b-nav-item-dropdown>
</b-navbar-nav>
</b-navbar>
</div>
<!-- b-navbar-dropdown.vue -->
<b-nav-form>
Use <b-nav-form>
to place inline form controls into your navbar
<div>
<b-navbar type="light" variant="light">
<b-nav-form>
<b-form-input class="mr-sm-2" placeholder="Search"></b-form-input>
<b-button variant="outline-success" class="my-2 my-sm-0" type="submit">Search</b-button>
</b-nav-form>
</b-navbar>
</div>
<!-- b-navbar-form.vue -->
Input groups work as well:
<div>
<b-navbar type="light" variant="light">
<b-nav-form>
<b-input-group prepend="@">
<b-form-input placeholder="Username"></b-form-input>
</b-input-group>
</b-nav-form>
</b-navbar>
</div>
<!-- b-navbar-form-inputs.vue -->
<b-navbar-toggle>
and <b-collapse is-nav>
Navbars are not responsive by default, but you can easily modify them to change that. Responsive
behavior depends on our <b-collapse>
component.
Wrap <b-navbar-nav>
components in a <b-collapse is-nav>
(remember to set the is-nav
prop!)
to specify content that will collapse based on a particular breakpoint. Assign a document unique
id
value on the <b-collapse>
.
Use the <b-navbar-toggle>
component to control the collapse component, and set the target
prop
of <b-navbar-toggle>
to the id
of <b-collapse>
.
Set the toggleable
prop on <b-navbar>
to the desired breakpoint you would like content to
automatically expand at. Possible toggleable
values are sm
, md
, lg
and xl
. Setting
toggleable
to true
(or an empty string) will set the navbar to be always collapsed, while
setting it to false
(the default) will disable collapsing (always expanded).
<b-navbar-toggle>
components are left-aligned by default, but should they follow a sibling element
like <b-navbar-brand>
, they'll automatically be aligned to the far right. Reversing your markup
will reverse the placement of the toggler.
See the first example on this page for reference, and also refer to
<b-collapse>
for details on the collapse component.
Navbars are hidden by default when printing. Force them to be printed by setting the print
prop.
Also see <b-nav>
for additional components and sub-component aliases.
