Remove / Hide Sidebar (Categories, Actions, Currency) on Mobile – Standard Cart

[kashif rasool]

Hi everyone,

I’m currently working with the Standard Cart order form template in WHMCS and trying to improve the mobile user experience.

On mobile devices, the sidebar (showing Categories, Actions, and Currency) appears at the top of the cart page, which negatively affects the user experience and conversions.

I’ve identified the related template files:

• sidebar-categories.tpl
• sidebar-categories-collapsed.tpl
• sidebar-categories-selector.tpl

I attempted the following:

• Removed the mobile block from sidebar-categories.tpl
• Emptied sidebar-categories-collapsed.tpl
• Cleared template cache

However, the sidebar is still showing on mobile.

What I want to achieve:

• Hide/remove the sidebar only on mobile devices
• Keep the desktop sidebar unchanged

Questions:

1. Is there another file (like viewcart.tpl or a hook) that controls the mobile sidebar output?
2. Is WHMCS injecting this via JS or another include that I might be missing?
3. What is the recommended way to disable the mobile sidebar cleanly?

Any help or direction would be greatly appreciated.

Thanks in advance!
