Blazorise Bar component

A responsive navbar that can support images, links, buttons, and dropdowns.

The Bar component is a responsive and versatile navigation bar that can be used as a top menu in Horizontal mode or as a sidebar in one of the three Vertical modes.

<Bar> main container
- <BarBrand> Horizontal: the left side, always visible. Vertical: top of Bar branding.
- <BarToggler> Horizontal: toggles the bar. Vertical: read more below.
- <BarMenu> Horizontal: the right side, hidden on breakpoint. Vertical: contains the core menu elements.
  - <BarStart> Horizontal: left side menu. Vertical: sticky top menu.
  - <BarEnd> Horizontal: right side menu. Vertical: sticky bottom menu.
    - <BarItem > each single item of the bar menu
      - <BarLink> item link or button
        <BarIcon> icon for Bar item (required for BarMode.VerticalSmall)
      - <BarDropdown> dropdown container (or popout for BarMode.VerticalPopout)
        <BarDropdownToggle> dropdown trigger
        
        <BarDropdownMenu> the dropdown menu, which can include bar items and dividers for BarMode.VerticalPopout)
        <BarDropdownItem> each single item of the dropdown menu
        
        <BarDropdownDivider> Divider that can be placed between BarDropdownItem’s.
        
        <BarDropdown> by adding this again inside the menu, you will create nested dropdowns

            </BarItem>
        </BarEnd>
    </BarMenu>
</Bar>

Vertical Bar (Sidebar)

When using the Bar in one of the Vertical modes for the purpose of a Sidebar, you need to place it inside the LayoutSiderContent component. Please see the Layout docs for more information on setup with Sidebar.

<Bar Mode="BarMode.VerticalInline"
     CollapseMode="BarCollapseMode.Small"
     Breakpoint="Breakpoint.Desktop"
     NavigationBreakpoint="Breakpoint.Tablet"
     ThemeContrast="ThemeContrast.Dark">
    <BarBrand>
        <BarItem>
            <BarLink To="#">
                <BarIcon IconName="IconName.Dashboard" />
                Blazorise Demo
            </BarLink>
        </BarItem>
    </BarBrand>
    <BarMenu>
        <BarStart>
            <BarItem>
                <BarLink To="#home">
                    <BarIcon IconName="IconName.Dashboard" />
                    Home
                </BarLink>
            </BarItem>
            <BarItem>
                <BarLink To="#docs">Documentation</BarLink>
            </BarItem>
            <BarItem>
                <BarDropdown>
                    <BarDropdownToggle>
                        <BarIcon IconName="IconName.Edit" />
                        Dropdown
                    </BarDropdownToggle>
                    <BarDropdownMenu>
                        <BarDropdownItem>Action</BarDropdownItem>
                        <BarDropdownItem>Another action</BarDropdownItem>
                    </BarDropdownMenu>
                </BarDropdown>
            </BarItem>
        </BarStart>
    </BarMenu>
</Bar>

Note: The BarIcon is required for each BarLink or BarDropdownToggle when using BarMode.VerticalSmall or BarCollapseMode.Small, in order for it work correctly. For a demo of the Vertical bar in action, please check out this Blazorise demo.

Right-aligned Vertical Bar

You can create a right-aligned Vertical style Bar easily by following two key principals.

Using the Layout to accommodate the right-align bar, by putting the LayoutSider section after the Layout section (see in example below).
Adding RightAligned to ALL BarDropdownMenu within the Vertical bar.

Right-aligned vertical bar example:

<Layout Sider>
    <LayoutSider>
        <LayoutSiderContent>
            <Bar Mode="BarMode.VerticalInline" CollapseMode="BarCollapseMode.Small"
                 Breakpoint="Breakpoint.Desktop"
                 Background="Background.Light"
                 ThemeContrast="ThemeContrast.Light">
                <BarBrand>
                    <BarItem>
                        <BarLink To="#">
                            <BarIcon IconName="IconName.Dashboard" />
                            Example
                        </BarLink>
                    </BarItem>
                </BarBrand>
                <BarMenu>
                    <BarStart>
                        <BarItem>
                            <BarDropdown RightAligned>
                                <BarDropdownToggle>
                                    <BarIcon IconName="IconName.Edit" />
                                    Toggle
                                </BarDropdownToggle>
                                <BarDropdownMenu>
                                    <BarDropdownItem>Action</BarDropdownItem>
                                    <BarDropdownItem>Another action</BarDropdownItem>
                                </BarDropdownMenu>
                            </BarDropdown>
                        </BarItem>
                    </BarStart>
                </BarMenu>
            </Bar>
        </LayoutSiderContent>
    </LayoutSider>
</Layout>

Vertical Bar Toggler

The BarToggler for Vertical Bar supports 2 modes:

BarTogglerMode.Normal (default)
BarTogglerMode.Popout

These 2 modes, along with an external implementation, provides 3 easy to configure implementations.

1. Inline

By simply adding the BarToggler anywhere inside the Vertical Bar component (at the top level), you will have an inline toggler added to your bar at this location.

<Bar Mode="BarMode.VerticalInline"
     Breakpoint="Breakpoint.Desktop"
     Background="Background.Light"
     ThemeContrast="ThemeContrast.Light">
    <BarToggler />
    <BarBrand>
        <BarItem>
            <BarLink To="#">
                <BarIcon IconName="IconName.Dashboard" />
                Example
            </BarLink>
        </BarItem>
    </BarBrand>
    <BarMenu>
        <BarItem>Example</BarItem>
    </BarMenu>
</Bar>

2. Popout Once again, by simply adding the BarToggler anywhere inside the Vertical Bar component (at the top level), and setting the Mode to Popout you will have an popout toggler added to your bar at this location.

<Bar Mode="BarMode.VerticalInline"
     Breakpoint="Breakpoint.Desktop"
     Background="Background.Light"
     ThemeContrast="ThemeContrast.Light">
    <BarBrand>
        <BarItem>
            <BarLink To="#">
                <BarIcon IconName="IconName.Dashboard" />
                Blazorise Demo
            </BarLink>
        </BarItem>
    </BarBrand>
    <BarToggler Mode="BarTogglerMode.Popout" />
    <BarMenu>
        <BarItem>Popout!</BarItem>
    </BarMenu>
</Bar>

3. External (controlled by Top Bar) For an externally controlled BarToggler, you need to be using the top bar. Where you have a top bar and vertical bar, you can add multiple BarTogglers to the top bar and choose to have one of these control the vertical bar by simply setting the Bar property. In the example below, we will create two BarTogglers inside the top bar.

One to control the Vertical Bar (closest to it)
One to control the Top Bar (at the opposite end)

<Layout Sider>
    <LayoutSider>
        <LayoutSiderContent>
            <Bar @ref="@sidebar" Mode="BarMode.VerticalInline"
                 Breakpoint="Breakpoint.Desktop"
                 Background="Background.Light"
                 ThemeContrast="ThemeContrast.Light">
                <BarItem>Example</BarItem>
            </Bar>
        </LayoutSiderContent>
    </LayoutSider>
    <Layout>
        <LayoutHeader Fixed>
            <Bar Mode="BarMode.Horizontal"
                 Background="Background.Light"
                 ThemeContrast="ThemeContrast.Light">
                <BarToggler Bar="@sidebar" />
                <BarBrand>
                    <BarItem>
                        <BarLink To="#">
                            <BarIcon IconName="IconName.Dashboard" />
                            Example
                        </BarLink>
                    </BarItem>
                </BarBrand>
                <BarMenu>
                    <BarItem>Example</BarItem>
                </BarMenu>
                <BarToggler />
            </Bar>
        </LayoutHeader>
    </Layout>
</Layout>

@code {
    private Bar sidebar;
}

Nested Dropdowns

To create nested BarDropdowns, you can simply add a BarDropdown component inside the structure of an existing BarDropdownMenu.

<Bar Breakpoint="Breakpoint.Desktop"
     Background="Background.Light"
     ThemeContrast="ThemeContrast.Light">
    <BarMenu>
        <BarStart>
            <BarItem>
                <BarDropdown>
                    <BarDropdownToggle>
                        Top-level toggler
                    </BarDropdownToggle>
                    <BarDropdownMenu>
                        <BarDropdownItem>
                            Top-level item
                        </BarDropdownItem>
                        <BarDropdown>
                            <BarDropdownToggle>
                                Nested toggler
                            </BarDropdownToggle>
                            <BarDropdownMenu>
                                <BarDropdownItem>
                                    Nested item
                                </BarDropdownItem>
                            </BarDropdownMenu>
                        </BarDropdown>
                    </BarDropdownMenu>
                </BarDropdown>
            </BarItem>
        </BarStart>
    </BarMenu>
</Bar>

Header on top
