Django admin: use checkboxes in list view in list_filter()

Question

I have a model Transaction with a ForeignKey to another model (TransactionState) on state field. So in admin.py I have:

class TransactionAdmin(admin.ModelAdmin):
    ...
    list_filter = ('state', )
    ...

In TransactionState I have records like "paid", "unpaid", "delivered", "canceled", Etc. and it works fine but I want to be able to filter using checkboxes to allow multiple selection like "paid" OR "delivered". It's possible?

Answer 1

For all models

You can easily override the django admin templates to customize the admin UI.

To edit the sidebar filter, just add a templates/admin/filter.html file, and write your custom HTML with radio buttons.

Note that this will change the sidebar filter for all models.

For a single model

If you want to change the filter for a single model, you can specify a template for a ListFilter:

class FilterWithCustomTemplate(admin.SimpleListFilter):
    template = "custom_template.html"

Example

As a reference example, check is the default template for filter.html.
