A simple jQuery javascript that collapses all stacked inline rows for better handling of large inline fieldsets.

It also adds "Show"/"Hide"-buttons for showing/hiding each row, which could be customized and styled using css.

Usage (see below for example):

Include the javascript on your admin page, together with jQuery, and it'll automatically affect all stacked inlines.

Works with

Django 3.1.4 (Might work with other versions with or without adjustments, but not tested)

Use example:

admin.py:

class DateInline(admin.StackedInline):
    model = Date
    extra = 10

class EventAdmin(admin.ModelAdmin):    
    inlines = [DateInline]

    class Media:
        js = ['js/collapsed-stacked-inlines.js']

admin.site.register(Event, EventAdmin)
