**What It Is**
This is a JavaScript-based solution to dynamically add and remove forms in formsets and inlineformsets. It requires jQuery.
Originally based on this Snippet: https://djangosnippets.org/snippets/1389/
I have done a lot of work to make it OO, and am using it in production on pages with multiple inlineformsets, and even nested inlineformsets (I call it, "Inlineformset Inception").
My hope is that the code and example are enough to show how it works.
**Usage Details**
In the example usage, I am using a CSS class, 'light', to make every other form have a light background color. My form placeholder is an element with an ID of 'formset-placeholder' (the default). And the form selector is a class name of 'dynamic-form' (the default).
When I have time, I will create a GitHub repository with the code and completed examples.

Having spent ages trying out various admin inline ordering packages and examples I found on here and elsewhere I failed to find a single one that did what I was after in the way I wanted or that worked, so I wrote one!
The general idea for this version was to be done purely in javascript, no additional methods or parameters required on your models, it's designed to be stuck in a js file and included in your admin class Media js parameter:
class Media:
js = ['js/admin/widget_ordering.js', ]
Your model should have an integer column for sorting on, the name of this column should go in the 'sort_column' parameter at line 3 and your model should also obviously specify this in it's Meta 'ordering' class:
class Meta:
ordering = ('rank',)
That's it! This is a pretty basic implementation that adds simple up and down buttons next to the sort order field, if you want to adapt this to use drag and drop or something, please feel free!
