Hi,

It's possible, and very easy. If you don't have be worry about GDPR law, you can set it from Template Options > Typography > Custom: On

1. In Custom Selectors area copy & paste:

.offcanvas-menu .offcanvas-inner ul.menu li a,
.offcanvas-menu .offcanvas-inner ul.menu > li a,
.offcanvas-menu .offcanvas-inner ul.menu ul

2. Choose font that you want
3. And Save settings

EXAMPLE

BTW

You can do the same using Custom CSS, if that font was used for different part of template.

please mark topic as solved ;] thx
