DF Tools
Demo Framework Tools are a generic library of modules that make a number of functions available. Most of these act as wrappers for enabling DF friendly configurations of popular modules. For example, df_tools_og enables Organic Groups and configures it for general demo usage. Others provide default block types or widgets that can be used by panels such as slideshows, hero banners and more. We also provide tools that allow demos to be color customized based on external urls with df_tools_color.
