How to hide some widgets in mobile version of site ?

It’s entirely possible. I recommend asking at https://www.ads-software.com/support/theme/hueman#postform so the theme’s developers and support community can help you with this.

Simple as adding css

@media (max-width: 960px) {
.widget { display: none; }
}

NOTE: you’ll need the replace .widget with the specific class or ID of your widget and you might have to play with the width

Thanks for sharing that!
