Today we looked into how to add the fields in the admin side.
We had already created a form last time when we were trying to do in admin directly except the form should be a ModelForm instead of a simple form.
After searching online and help from Jasvir, we have the form added recursively (for multiple items).
Next I am looking into correcting the jQuery and AJAX implementation.
On the other note, I’ve passed my final evaluation in GSoC.
