Changing width trigger for menu's responsiveness, media query

I need to change the width in which the menu will respond to be mobile friendly.
I don't see a media query option in the settings.

Dear eclipsemedia.

You can change the width in file .../modules/mod_jux_megamenu/assets/css/style_responsive line 14
