When to Use This Skill

Use this skill when you need to:

• Build navigation breadcrumbs for single-page applications (SPAs) to show the user's current position in a hierarchy
• Auto-generate breadcrumb trails based on the current URL path
• Create custom navigation sequences with dynamic item management (add/remove items at runtime)
• Handle overflow scenarios with many breadcrumb items (collapsed, menu, wrap, scroll modes)
• Customize visual appearance with icons, images, separators, or templates
• Implement templated breadcrumb layouts using Chip components or custom renderers
• Enable/disable navigation based on business logic or user roles

The Syncfusion Blazor Breadcrumb component provides built-in URL parsing, responsive overflow handling, and templating capabilities to simplify hierarchical navigation UIs.

Quick Start Example

Basic breadcrumb with explicit items:

@using Syncfusion.Blazor.Navigations

<SfBreadcrumb>
    <BreadcrumbItems>
        <BreadcrumbItem IconCss="e-icons e-home" Url="https://example.com/home"></BreadcrumbItem>
        <BreadcrumbItem Text="Products" Url="https://example.com/products"></BreadcrumbItem>
        <BreadcrumbItem Text="Electronics" Url="https://example.com/products/electronics"></BreadcrumbItem>
        <BreadcrumbItem Text="Laptops"></BreadcrumbItem>
    </BreadcrumbItems>
</SfBreadcrumb>

Auto-generated breadcrumb from current URL:

@using Syncfusion.Blazor.Navigations

<SfBreadcrumb></SfBreadcrumb>

Common Patterns

Pattern 1: Icon + Text Items

Combine icons with text for visual hierarchy and quick scanning:

<SfBreadcrumb>
    <BreadcrumbItems>
        <BreadcrumbItem IconCss="e-icons e-home" Url="/"></BreadcrumbItem>
        <BreadcrumbItem IconCss="e-icons e-folder-open" Text="Documents" Url="/docs"></BreadcrumbItem>
        <BreadcrumbItem Text="Projects"></BreadcrumbItem>
    </BreadcrumbItems>
</SfBreadcrumb>

Pattern 2: Handling Long Breadcrumb Trails

Use MaxItems with OverflowMode to manage deep hierarchies:

<SfBreadcrumb MaxItems="4" OverflowMode="BreadcrumbOverflowMode.Menu">
    <BreadcrumbItems>
        <BreadcrumbItem Text="Home" Url="/"></BreadcrumbItem>
        <BreadcrumbItem Text="Category 1" Url="/cat1"></BreadcrumbItem>
        <BreadcrumbItem Text="Category 2" Url="/cat1/cat2"></BreadcrumbItem>
        <BreadcrumbItem Text="Category 3" Url="/cat1/cat2/cat3"></BreadcrumbItem>
        <BreadcrumbItem Text="Current Page"></BreadcrumbItem>
    </BreadcrumbItems>
</SfBreadcrumb>

Pattern 3: Dynamic Item Management

Add/remove items at runtime based on user actions:

@using Syncfusion.Blazor.Navigations

<SfBreadcrumb Items="@breadcrumbItems"></SfBreadcrumb>

<button @onclick="AddItem">Add Item</button>
<button @onclick="RemoveItem">Remove Item</button>

@code {
    List<BreadcrumbItem> breadcrumbItems = new List<BreadcrumbItem>
    {
        new BreadcrumbItem { IconCss = "e-icons e-home" },
        new BreadcrumbItem { Text = "Products" }
    };

    private void AddItem()
    {
        breadcrumbItems.Add(new BreadcrumbItem { Text = "New Item" });
    }

    private void RemoveItem()
    {
        if (breadcrumbItems.Count > 0)
            breadcrumbItems.RemoveAt(breadcrumbItems.Count - 1);
    }
}

Pattern 4: Custom Separator with Template

Use SeparatorTemplate for custom visual separators:

<SfBreadcrumb>
    <BreadcrumbItems>
        <BreadcrumbItem Text="Home" Url="/"></BreadcrumbItem>
        <BreadcrumbItem Text="Products" Url="/products"></BreadcrumbItem>
        <BreadcrumbItem Text="Details"></BreadcrumbItem>
    </BreadcrumbItems>
    <BreadcrumbTemplates>
        <SeparatorTemplate>
            <span class="e-icons e-arrow"></span>
        </SeparatorTemplate>
    </BreadcrumbTemplates>
</SfBreadcrumb>
