Frequently Asked Questions

Common questions about CSS & JavaScript Toolbox

The CJT plugin was created to help website authors write or add their own code. The plugin allows you to contribute to your Wordpress installation code via a simple web interface, where you can modify and extend the functionality and appearance of your website by writing code directly into CJT code blocks. Some typical examples can include changing the look of a specific page by adding some CSS code; adding functionality to a page with PHP; or making a page more interactive by adding some JavaScript.
The CJT code block is the most fundamental unit for writing code and to associate it with specific Wordpress requests via the assignment panel.
The assignment panel is a tabs window, which appears on the right side of the code block editor and is used to assign/apply the code block into specific requests. These assignments include: Pages, Posts, Custom Posts, Tags, and Categories. Auxiliary sections such as Entire Website, Website Backend, All Pages, All Posts, Recent Posts, Blog Index, All Categories, Search Pages, All Archives, Tag Archives, Author Archives, Attachment Pages, 404 Error Pages. Advanced sections such as URLs, or Regular Expressions (Regex).
These are premium features, which are only available for our CJT PLUS plugin. Click here to purchase a license for any of our premium CJT PLUS products.
Yes. You can select any number of items you need, there is no limitation regarding this.
Yes. It's one of the most useful features that CJT supports as it allows you to manage/split your codes into several code blocks, allowing you to override code in a former (or lower-ordered) code block.
These lists with checkboxes represent all of your WordPress Pages, Posts, Categories and Custom Posts that your entire website contains. It also supports sub-pages and sub-categories, which you will find in there.
As there are a number of requests that are not available as normal Wordpress items (e.g. Pages, Posts, etc) but since it's commonly required and most likely to be used, you will find them pre-defined in the Auxiliary tab. In the Auxiliary tab you can find things like: Entire Website, Blog Index, Author, 404 error, Front-end, Admin backend and much more!
Pages, Posts, Custom Posts and Categories tabs are created to simplify the assignment process for all types of users. Using URLs is great for fast performance as it requires less time to evaluate/identify the request! However, not all things can be done through the URLs tab. For example, applying a single block to a Category index page and all its sub-categories.
The Advanced Expression tab allows you to fully control what requests to integrate into the code block by using Regular Expressions. In other words, allowing CJT users to define more requests to assign the code block to.
