The Category Field - Category fields are lists of pre-defined ways to label a specific kind of content. In the example image below, the Category Field displays a list of 4 pre-defined Categories. Clicking on one of them, in this case “Movie Genres”, applies the Category label to the content as soon as it is saved or published. Category fields are typically used when the content being created is pulled dynamically by the individual Categories on several different pages. Using this powerful taxonomy method, content contributors can publish content that will dynamically appear, filtered by category on HTML pages, without ever visiting the HTML page itself.
