This framework plugin makes adding options to the WordPress admin area very simple, yet flexible. It all works using a single action and an array.
You can download the latest version from the WordPress plugin repository. If you prefer to install it from Github, make sure to run composer install before using it in order to download the necessary dependencies.
For a detailed guide and reference on how to use this framework, please read the Wiki on Github. Once you get familiar with the options you have, you will be able to create complex options interfaces in just a few minutes.
If you have ideas on how to improve the plugin or if you discover a bug, I would appreciate if you shared them with me, right here on Github. In either case, please open a new issue here!
You can also contribute to the plugin by translating it. Simply visit translate.wordpress.org to get started. Note that you can help not only translating the plugin, but also the underlying library WPDLib.
