Breadcrumb

Overview

Displays a navigational breadcrumb trail showing the current page’s position within the site hierarchy.

Block name: method/bc
Category: method-component-blocks
Supports: align (wide, full)
Render type: Dynamic (PHP render_callback)
Inner blocks: No

Usage

The Breadcrumb block renders a dynamic breadcrumb trail based on the current page’s position within the site. The trail structure is determined by Method’s theme options (method_options), which control separator characters, home link inclusion, current item display, and per‑post‑type/taxonomy parent behaviors.

Insert the block in a header template part or at the top of a page template. The editor shows a static placeholder with three sample items. The actual breadcrumb trail is generated server‑side.

Attributes

Attribute	Type	Default	Description
`textColor`	`string`	—	Text color of the trail
`linkColor`	`string`	—	Link color; also applied to the last item
`responsiveSettings`	`object`	(standard breakpoints)	Spacing, alignment, gap, and color per breakpoint

Control Sets

Component	Panel	Breakpoints	Notes
`MethodAlignmentControls`	Alignment	base, mobile, tablet, wide	`alignItems`, `justifyContent`
`MethodSpacingControls`	Spacing	base, mobile, tablet, wide	Padding (all sides), Margin (top/bottom), Gap (horizontal/vertical)
`MethodColorControls`	Colors	global	`textColor`, `linkColor`
`MethodResponsiveTabs`	Responsive	mobile, tablet, wide	—
`MethodStyleTag`	—	—	Scoped editor styles

Data

The breadcrumb trail is built entirely server‑side from the method_options option. Key option fields:

Option Key	Description
`bc_sep`	Separator character (default: `/`)
`bc_home`	Whether to include a “Home” link at the start
`bc_current`	Whether to include the current page/post as the final item
`bc_sep_inclusion`	Whether to show the separator after the last item
`bc_{post_type}_behavior`	Parent trail behavior: a page ID (walks up hierarchy) or `archive_{cpt}` (links to archive)
`bc_{post_type}_archive`	Whether to include the post type archive in the trail
`bc_{post_type}_label`	Custom label for the post type archive link
`bc_{taxonomy}_behavior`	Parent trail behavior for taxonomy archives

Custom title override

Both posts and terms support a custom breadcrumb title via meta:

Posts/pages: _method_bc_title post meta
Terms: _method_bc_title term meta

When set, this overrides the default get_the_title() / $term->name in the breadcrumb trail.

Trail building logic

The PHP render callback determines the trail based on the current page type:

Context	Trail Logic
`is_singular()`	Resolves configured behavior → optional archive link → page ancestors → current item
`is_tax()` / `is_category()` / `is_tag()`	Resolves configured behavior → term ancestors → current term
`is_post_type_archive()`	Resolves configured behavior → current archive
`is_home()`	Blog page title
`is_page()`	Page ancestors → current page
`is_search()`	“Search Results”
`is_404()`	“Not Found”

Frontend Rendering

<nav class="wp-block-method-bc" aria-label="Breadcrumb">
  <ol class="method-breadcrumb-list">
    <li class="method-breadcrumb-item">
      <a href="/">Home</a>
      <span class="method-breadcrumb-sep" aria-hidden="true">/</span>
    </li>
    <li class="method-breadcrumb-item">
      <a href="/parent/">Parent Page</a>
      <span class="method-breadcrumb-sep" aria-hidden="true">/</span>
    </li>
    <li class="method-breadcrumb-item">
      <span aria-current="page">Current Page</span>
    </li>
  </ol>
</nav>

The current (final) item renders as a <span aria-current="page"> instead of a link. Separator visibility on the last item is controlled by the bc_sep_inclusion option.

Filters

This block does not currently expose dedicated PHP filters for trail modification. Trail behavior is configured entirely through the method_options option page. CSS customization targets #method-{id} selectors and the .method-breadcrumb-* class structure.
