Only One Category is a WordPress plugin designed to streamline the category selection process for posts. By converting the category selectors into radio buttons, it ensures that users can only select a single category for each post. This feature not only simplifies the user experience but also maintains the integrity of the site's layout and functionality by preventing accidental or intentional selections of multiple categories.

This plugin is particularly beneficial for those who aim for a consistent editorial style without the hassle of managing category assignments. With Only One Category, users can focus on content creation while the plugin enforces the single-category rule, making it an essential tool for maintaining clarity and organization in WordPress blog management.
