Help and recommendations for product and category pages

Hi All, we are currently building bosecom.co.uk - the next IT superstore, help and recommendations required. I am currently making a dropdown search, please let me know if anyone here is free to message and share ideas.

Thanks

Currently need help linking this file to the front end?

root_dir/ext/bosecom/ajax_search.inc.php

anyone know how i can do this? I have attempted posting to this and can echo out content if i run a get request

Place this line on the frontend where you want to appear the script

When the frontend fires an ajax request on this script, you can also put this script here:

root_dir/pages/ajax/ajax_search.inc.php

And your js in the frontend could look something like this:

$.ajax({
    url: '', // notice: skip inc.php from name
    type: "POST",
    data: {
    ...

Thanks i figured it out, I have a new issue, on my site https://repairs.bosecom.org.uk I have this issue where there is space outside the content area:

can you assist me in finding out why?

I figured it out Plugin:
New Products Page -  something with this is causing the page to be extended?
