Navs and tabs

Documentation and examples for how to use Bootstrap's included navigation components.

Base nav

Navigation available in Bootstrap share general markup and styles, from the base NavList component to the active and disabled states. Swap modifier classes to switch between each style.

The base NavList component is built with flexbox and provide a strong foundation for building all types of navigation components. It includes some style overrides (for working with lists), some link padding for larger hit areas, and basic disabled styling.

vue
<template>
 <NavList>
  <NavItem>
   <NavLink active>
    Active
   </NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink disabled>
    Disabled
   </NavLink>
  </NavItem>
 </NavList>
</template>
vue
<template>
 <Nav>
  <NavLink active>
   Active
  </NavLink>
  <NavLink>Link</NavLink>
  <NavLink>Link</NavLink>
  <NavLink disabled>
   Disabled
  </NavLink>
 </Nav>
</template>

Available styles

Change the style of NavLists component with modifiers and utilities. Mix and match as needed, or build your own.

Horizontal alignment

Change the horizontal alignment of your nav with flexbox utilities . By default, navs are left-aligned, but you can easily change them to center or right aligned.

Centered with justify-content="center" attribute:

vue
<template>
 <NavList justify-content="center">
  <NavItem>
   <NavLink active>
    Active
   </NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink disabled>
    Disabled
   </NavLink>
  </NavItem>
 </NavList>
</template>

Right-aligned with justify-content="end" attribute:

vue
<template>
 <NavList justify-content="end">
  <NavItem>
   <NavLink active>
    Active
   </NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink disabled>
    Disabled
   </NavLink>
  </NavItem>
 </NavList>
</template>

Vertical

Stack your navigation by changing the flex item direction with the flex-direction="column" attribute. Need to stack them on some viewports but not others? Use the responsive versions (e.g., flex-direction="sm-column").

vue
<template>
 <NavList flex-direction="column">
  <NavItem>
   <NavLink active>
    Active
   </NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink disabled>
    Disabled
   </NavLink>
  </NavItem>
 </NavList>
</template>

As always, vertical navigation is possible without NavItems component, too.

vue
<template>
 <NavList flex-direction="column">
  <NavLink active>
   Active
  </NavLink>
  <NavLink>Link</NavLink>
  <NavLink>Link</NavLink>
  <NavLink disabled>
   Disabled
  </NavLink>
 </NavList>
</template>

Tabs

Takes the basic nav from above and adds the nav="tabs" attribute to generate a tabbed interface. Use them to create tabbable regions with our tab JavaScript plugin.

vue
<template>
 <NavList nav="tabs">
  <NavItem>
   <NavLink active>
    Active
   </NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink disabled>
    Disabled
   </NavLink>
  </NavItem>
 </NavList>
</template>

Pills

Take that same HTML, but use nav="pills" attribute instead:

vue
<template>
 <NavList nav="pills">
  <NavItem>
   <NavLink active>
    Active
   </NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink disabled>
    Disabled
   </NavLink>
  </NavItem>
 </NavList>
</template>

Take that same HTML, but use nav="underline" attribute instead:

vue
<template>
 <NavList nav="underline">
  <NavItem>
   <NavLink active>
    Active
   </NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink disabled>
    Disabled
   </NavLink>
  </NavItem>
 </NavList>
</template>

Fill and justify

Force your NavList's contents to extend the full available width one of two modifier classes. To proportionately fill all available space with your NavItems component, use fill attribute. Notice that all horizontal space is occupied, but not every nav item has the same width.

vue
<template>
 <NavList
  nav="pills"
  fill
 >
  <NavItem>
   <NavLink active>
    Active
   </NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Much longer nav link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink disabled>
    Disabled
   </NavLink>
  </NavItem>
 </NavList>
</template>

When using a Nav component-based navigation, you can safely omit NavItem compoentnt as only NavLink comoponent is required for styling NavLink component elements.

vue
<template>
 <Nav
  nav="pills"
  fill
 >
  <NavLink active>
   Active
  </NavLink>
  <NavLink>Much longer nav link</NavLink>
  <NavLink>Link</NavLink>
  <NavLink disabled>
   Disabled
  </NavLink>
 </Nav>
</template>

For equal-width elements, use justified attribute. All horizontal space will be occupied by nav links, but unlike the fill attribute above, every nav item will be the same width.

vue
<template>
 <NavList
  nav="pills"
  justified
 >
  <NavItem>
   <NavLink active>
    Active
   </NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Much longer nav link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink disabled>
    Disabled
   </NavLink>
  </NavItem>
 </NavList>
</template>

Similar to the fill component example using a Nav component-based navigation.

vue
<template>
 <Nav
  nav="pills"
  justified
 >
  <NavLink active>
   Active
  </NavLink>
  <NavLink>Much longer nav link</NavLink>
  <NavLink>Link</NavLink>
  <NavLink disabled>
   Disabled
  </NavLink>
 </Nav>
</template>

Working with flex utilities

If you need responsive nav variations, consider using a series of flexbox utilities . While more verbose, these utilities offer greater customization across responsive breakpoints. In the example below, our nav will be stacked on the lowest breakpoint, then adapt to a horizontal layout that fills the available width starting from the small breakpoint.

vue
<template>
 <Nav
  nav="pills"
  flex-direction="column sm-row"
 >
  <NavLink
   flex-fill="sm"
   text-alignment="sm-center"
   active
  >
   Active
  </NavLink>
  <NavLink
   flex-fill="sm"
   text-alignment="sm-center"
  >
   Much longer nav link
  </NavLink>
  <NavLink
   flex-fill="sm"
   text-alignment="sm-center"
  >
   Link
  </NavLink>
  <NavLink
   flex-fill="sm"
   text-alignment="sm-center"
   disabled
  >
   Disabled
  </NavLink>
 </Nav>
</template>

Regarding accessibility

If you're using navs to provide a navigation bar, be sure to add a role="navigation" to the most logical parent container of the NavList component, or wrap a Nav component around the whole navigation. Do not add the role to the NavList component itself, as this would prevent it from being announced as an actual list by assistive technologies.

Using dropdowns

Add dropdown menus with a little extra HTML and the dropdowns JavaScript plugin .

Tabs with dropdowns

vue
<template>
 <NavList nav="tabs">
  <NavItem>
   <NavLink active>
    Active
   </NavLink>
  </NavItem>
  <NavItemDropdown>
   <NavItemDropdownToggle>Dropdown button</NavItemDropdownToggle>
   <DropdownMenu>
    <DropdownItem to="/">
     Action
    </DropdownItem>
    <DropdownItem>Another action</DropdownItem>
    <DropdownItemDivider />
    <DropdownItem>Something else here</DropdownItem>
   </DropdownMenu>
  </NavItemDropdown>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink disabled>
    Disabled
   </NavLink>
  </NavItem>
 </NavList>
</template>

Pills with dropdowns

vue
<template>
 <NavList nav="pills">
  <NavItem>
   <NavLink active>
    Active
   </NavLink>
  </NavItem>
  <NavItemDropdown>
   <NavItemDropdownToggle>Dropdown button</NavItemDropdownToggle>
   <DropdownMenu>
    <DropdownItem to="/">
     Action
    </DropdownItem>
    <DropdownItem>Another action</DropdownItem>
    <DropdownItemDivider />
    <DropdownItem>Something else here</DropdownItem>
   </DropdownMenu>
  </NavItemDropdown>
  <NavItem>
   <NavLink>Link</NavLink>
  </NavItem>
  <NavItem>
   <NavLink disabled>
    Disabled
   </NavLink>
  </NavItem>
 </NavList>
</template>
