Hello, I'm new to Oxwall and I really like the platform.  I'm developing a plug-in and I'm wondering if there is more in depth documentation.  I've gone through the crash course, etc. but it's not very detailed.

For instance, through examples and the crash course I know I can add a new field to a form as such:

$form = new Form('myform');

$field = new SelectBox($question->fieldName); 

$form->addElement($field);

Besides TextArea, TextField and TextArea, what other field types are there?  Is this documented somewhere?

Thanks,

Eric
