Breadcrumbs

Example of common breadcrumb item:

public class Breadcrumb : NavigationItem<Breadcrumb>
{
    public string Action { get; set; }
    public string Controller { get; set; }
    public string Area { get; set; }
}

IBreadcrumbNavigation<Breadcrumb> is the main service to get navigation. IBreadcrumbNavigation<Breadcrumb> created once per request within the scope.

For example, create _Breadcrumbs.cshtml view:

@using Structr.Navigation
@model IBreadcrumbNavigation<Breadcrumb>

<div class="navigation breadcrumbs">
    <h4 class="navigation-title">Breadcrumbs:</h4>
    <ul class="navigation-content">
        @foreach (var breadcrumb in Model)
        {
            <li>
                @if (breadcrumb.IsActive)
                {
                    @breadcrumb.Title
                }
                else
                {
                    <a href="@Url.Action(breadcrumb.Action, breadcrumb.Controller, new { area = breadcrumb.Area })">@breadcrumb.Title</a>
                }
            </li>
        }
    </ul>
</div>

Then you can inject IBreadcrumbNavigation<Breadcrumb> into _Layout.cshtml and use _Breadcrumbs.cshtml partial view to rendering breadcrumbs.

_Layout.cshtml:

@using Structr.Navigation
@inject IBreadcrumbNavigation<Breadcrumb> breadcrumbs

<partial name="_Breadcrumbs" model="breadcrumbs" />
