Radio Buttons for Taxonomies

Radio Buttons for Taxonomies

Details
View on WordPress

Replace the default taxonomy boxes with a custom metabox that uses radio buttons… effectively limiting each post to a single term in that taxonomy.

A plugin options page allows the user can select which taxonomies she’d like to switch to using the custom radio-button style metabox.

Originally based on the the class by Stephen Harris
