Only One Category vs Admin Columns

With a simple drag-and-drop interface you can: Add any column to posts, pages, users, media and comments Reorder and resize columns to match your workflow Choose from 200+ column types including custom fields, taxonomies and file data Display rich metadata such as images, dates, colors and relational fields Create clean overviews for even the most complex websites It works for any site from simple blogs to large WooCommerce stores.

Only One Category makes sure users only select one category for their post by making the selectors radio buttons, which only allow one category to be selected. Rather than spend all your time maintaining the editorial style of only putting posts into a single category, this plugin is a quick way for you to enforce that standard. It makes it impossible for a person to accidentally break your site’s layout of functionality by putting a post in multiple categories. They just can’t do it, whether by accident or intention.
