How can i include ajax in filter module.The page data should be refreshed without clicking the refine search button !

Hello Asthajain, I'm sorry to hear that you're having problems with the operation of OpenCart. If you are trying to change the filter function for OpenCart, then you should consult their development guide or forums for more information. Here's a link on the filters in their forum: OpenCart filter module. I apologize as we can't change the code for you because we did not develop the product. I hope this helps to point you in the right direction so that you can either make the change yourself, or at least communicate with the communities where others may be trying to do the same thing. Regards, Arnel C.
