How to implement the apply filters button? like on a stringshot?

Question

CMS

Hi friends, I'm interested in the question, how to implement a button like in the screenshot?
This site is made on Bitrix, I'm developing on wordpress + woocommerce.
That is, I chose the attributes, clicked apply ... And the process went on, even without the quantity, just a pop-up button. I tried all the plugins, there is no such function in free, not in paid Woocommerce plugins.

Answer 1

The problem for CMS developers is that sometimes you have to do something yourself :)
from the front, you need to execute an ajax request in which new filtering parameters are transmitted.
From the back end, you need to process this request and, with its parameters, make a new selection) which is eventually transferred back to the front end and replace it.

write yourself, if the dough is squeezed ...
Misha Rudastykh has three options for Ajax filters, BUT among them there is also no golden mean, only tips)))
just google his English site, in the Russian version there is one crap with glitches in the form of cropped ones (hello , Urgant!)) code pieces and articles are much older...
there are good paid filters, FasetWP for example
