The multi category search open the following link:
https://www.example.org/categories/16306,8128/search_type/order/

But I want this link:
https://www.example.org/categories/16334,8129/search_type/and/order/title/

Can you help me?

I resolved whit php echo
<?php echo mcsw_shortcode_handler('both'); ?>

Insteas If you want multiple category selection widget in page use this code:
[mcsw]

Hi antoniobon,

I added the plugin to my header using a customer widget area plugin which I called up in the header.php

But the search function only works on the home page. Any idea why this might be? I’d really appreciate any input.

There is holding page so go to:
