🚀 Features

  • Drag-and-drop taxonomy management — move posts between term columns or assign terms to posts.
  • Inline editing — rename, create, or delete terms without leaving the board.
  • Palette system — choose from 30+ color palettes (warm, cool, material, vivid, forest, etc.).
  • Dark-mode ready — automatically adapts when <html class="dark"> is active.
  • Two modes:
    • MECE Mode: posts grouped by taxonomy term.
    • Non-MECE Mode: draggable term cards assignable to posts.
  • Tailwind-compatible variables for easy integration with modern WP admin themes.
  • Taxonomy Kanban Block embeds compact visualizations in content

🧩 Modes Explained

🟩 Single MECE Mode

This mode enforces Mutual Exclusivity: each post is assigned to a single taxonomy term.
You’ll see one column per term (plus “Uncategorised”), with posts listed beneath.
Drag a post card from one column to another to reassign its taxonomy instantly.
Use the “+ Add Term” button to create new columns and rename them inline.

🟦 Multi Affinity Mode

This mode supports Collective Exhaustiveness: posts may belong to multiple terms.
On the left, you’ll see a draggable list of all terms (tags or other taxonomies).
On the right, posts appear as cards; drag one or more terms onto a post to assign them.
Click a term chip to remove it. Changes are saved live via AJAX.

🧭 Dashboard Widgets

The plugin includes a set of dashboard widgets for at-a-glance visibility:

  • MECE Overview Chart: Displays category distribution and orphaned posts.
  • Cumulative Flow Diagram (CFD): Shows how taxonomy assignments evolve over time.
  • Recent Changes: Lists the latest taxonomy edits (created, renamed, or moved).
  • Palette Preview: Displays the currently selected palette for the active taxonomy.

Widgets can be enabled or disabled under Screen Options → Dashboard Widgets in the WordPress admin.

    mece_create_term, mece_rename_term, mece_delete_term, mece_set_post_term, mece_add_post_term, mece_remove_post_term.
