i'll include my code first

Models:

Base.html: (for the navbar button)

views.py:

and this is the page:

So what i want to do is if the user click the button, the page is filtering and just return the book with requested genre.

I've tried to use jquery with function (as you can see in base.html), i've tried some of method in google but it filtering with get element byclassname.

Is it possible if not using jquery,ajax, etc?, if not it's ok but give me an explanation, because i don't really understand.
