Django Admin Stacked Inline

I've 3 models:-

class Category(models.Model):
    name = models.CharField(max_length=60)

class CategoryQuestions(models.Model):
    # Questions related to category.
    question_text = models.CharField(max_length=255)
    category = models.ForeignKey(Category)

class CategoryQuestionsOptions(models.Model):
    # Options related to each question.
    option = models.CharField(max_length=255)
    question = models.ForeignKey(CategoryQuestions)

I want that whenever I add a category, I must be able to add N questions and N options to each question.

Here is my admin.py

class CategoryQuestionsInline(admin.StackedInline):
    model = CategoryQuestions
    extra = 4


class CategoryAdmin(admin.ModelAdmin):
    inlines = [CategoryQuestionsInline]
    list_display = ('name', 'code', 'description')
    search_fields = ['name', 'code']

admin.site.register(Category, CategoryAdmin)

Currently, I;m able to add N questions while creating a new category. How can I create N options for each question while creating a new category on the same page,?
