How to hide price and items from menu

Is there no option in the theme customizer?

Alternatively you can use CSS to hide it:

.main-navigation .primer-wc-cart-menu {display:none!important;}

Thank you for your reply.
Can you please explain where I need to plcae the CSS?

In Appearance-Customise-Additional CSS

Clear, however it does not disappear, Any clue?

Try

.primer-wc-cart-menu {display:none!important;}

Still not working, any other suggestions?

Strange – works for me – I do see in the CSS that you have:

.primer-wc-cart-menu {
display: none !important; }
.main-navigation .primer-wc-cart-menu {
display: list-item !important; }

Try using this:
.primer-wc-cart-menu {
display: none !important; }
.main-navigation .primer-wc-cart-menu {
display: none !important; }

I have placed your latest code, however the price & items indication remains

That’s strange – it works for me: https://ibb.co/t2PYP5m
