README

Modularity Posts Extensions adds focused display behavior from Municipio LTS to the Posts module built into modern Municipio. It extends that module without owning or replacing it, restoring Municipio Extended, or depending on the deprecated standalone Modularity plugin.

Supported first port

The existing Posts module and its metadata remain the source of truth.
posts_display_as=mixed is exposed as Cards and list without a write migration.
The first two posts in Municipio's prepared order render as cards.
Remaining posts render as a compact title list.
Zero posts render no empty card or list shell; one or two posts render cards only.
Existing title, preamble, card field choices, archive link, post order, sticky-post precedence, and post sources remain owned by Municipio.

Taxonomy display, slider combinations, pagination changes, new data sources, and other LTS Posts layouts are intentionally outside this release.

Installation

Install municipio/wp-plugin-modularity-posts-extensions with Composer. Composer Installers places it in wp-content/plugins/modularity-posts-extensions through extra.installer-name.

The plugin supports modern Municipio only. The initial compatibility contract is verified against helsingborg-stad/municipio 6.43.2, where Modularity is bundled with the theme.

Data migration

No activation or write migration runs. The plugin preserves the existing field key and mixed value, so imported modules become editable and render correctly as soon as the plugin is active. Deactivation leaves stored metadata untouched.

Extension points

The plugin consumes these Municipio and ACF filters:

acf/render_field/key=field_571dfd4c0d9d9 renders the plugin-owned mixed option beside Municipio's current image choices without changing their field schema.
Modularity/Module/Posts/template selects the plugin-owned composition for mixed only.
Modularity/Module/posts/TemplatePath makes the plugin view discoverable during Modularity's initial template lookup.
/Modularity/externalViewPath combines the plugin view root with Municipio's Posts partials after the template has been selected.

The private template allowlist in Municipio 6.43.2 intentionally falls back to list preparation for unknown saved values. The plugin uses that prepared post-object contract and stops routing all formats except mixed.

Layout and accessibility

The plugin composes Municipio's current card, collection, typography, title, and archive-link partials. Plugin-owned CSS Grid uses the site's --grid-gap token and content-driven columns with an 18 rem minimum, without customer-specific breakpoints or copied LTS utilities.

Link semantics and interaction states remain owned by Municipio's components. The mixed view adds unique heading associations for list links and preserves link attributes prepared by Municipio.
