Hi,
Please note that you're using HikaShop 2.6.4 and not HikaShop 3.2.0
With HikaShop 2.6.4, you need to activate the "use boostrap design" setting of the HikaShop configuration for the listings to be responsive (display properly on mobile). This requires your template to support boostrap 2.
With HikaShop 3.2.0, the listings are responsive by default, without the need for bootstrap at all.
So you have 3 solutions:
- turn on the use boostrap design and make sure that your template supports boostrap 2 and it should do it
- update to HikaShop 3.2.0
- Add custom CSS to do the responsive yourself with @media queries.
