Comprehensive Demo PDF Form Elements

I am testing a PDF tool website and want to know all the different types of options and features available on PDF forms. I am aware of some, like radio buttons, checkboxes, and fillable fields, but I need someone to create a single PDF form that includes all possible options and features so I can test them at once. Ideally, a demo PDF form with every type of form element would save me the time of searching and testing multiple PDFs online.
