Adjust Admin Categories

What is Adjust Admin Categories?

Adjust Admin Categories is a focused utility plugin that modifies how category and custom taxonomy checkboxes behave in the WordPress post editor. Developed by Masahiro NAKASHIMA, it has been available for 12 years. The plugin currently has 10K+ active installs and holds a 5.0/5 rating from 4 reviews. Its primary goal is to stop the familiar frustration of a checkbox list jumping when you make a selection.

Instead of overhauling the entire admin area, this tool targets a specific pain point: the admin category meta box. It lets you change the default category box behavior in WordPress. For example, you can switch checkboxes to radio buttons or prevent parent categories from being selected. This makes it a precise solution for sites that need strict taxonomy control.

Key Features of Adjust Admin Categories

• Stop Checkbox Movement — Prevents the entire category list from shifting when you check or uncheck an item, keeping your view stable.
• Convert to Radio Buttons — Changes the category box behavior from multi-select checkboxes to single-select radio buttons, enforcing one category per post.
• Disable Parent Category Selection — Makes parent categories unselectable, allowing only child (sub) categories to be assigned to posts.
• Custom Taxonomy Support — Works with both built-in categories and any custom taxonomy box in the admin area, extending control to all taxonomies.
• Require Category Selection — Forces users to assign at least one category or taxonomy term before a post can be published or saved.
• Targeted Settings Panel — All adjustments are managed from a single page under Settings > Adjust Categories, keeping the interface simple.
• Lightweight Codebase — The plugin adds no bloat to the front end and only activates its logic on the post editing screen.

Who Should Use Adjust Admin Categories?

This plugin is ideal for site owners who manage content with strict categorization rules. Bloggers with a hierarchical category tree will benefit from disabling parent selection, ensuring posts are always filed under a specific sub-category. Agencies building client sites can use the radio button option to enforce a single-category policy, which is common for news or portfolio sites.

The plugin requires no coding skills. It is suitable for beginners who can navigate the WordPress admin menu. With 10K+ installs and a 5.0/5 score from 4 ratings, it has proven reliable for users who need to adjust category meta box WordPress behavior without hiring a developer.

Installation & Setup

Installation follows the standard WordPress process: upload the folder to /wp-content/plugins/ and activate from the Plugins screen. After activation, visit Settings > Adjust Categories to configure your preferences. The interface is minimal, offering checkboxes for each feature, making it beginner-friendly.

Support & Community

The plugin has earned a 100% five-star rating from its 4 reviews, with 0% one-star ratings. In the last two months, the support forum has recorded open threads. The developer, Masahiro NAKASHIMA, has maintained the plugin for 12 years, suggesting consistent attention to its small but dedicated user base.

Given the plugin's focused feature set and stable code, support needs appear minimal. The absence of recent unresolved threads indicates that existing documentation and the simple settings panel cover most user questions effectively.
