Hey Innovatetaos,
at the moment the theme does not imply such a option, since the “link URL” setting in the icon menu items has been envisaged to use for leading to other pages on the same website rather than opening external links, since the icon menu can be regarded as other in-site navigation. If you want all icon menu URLs to open in new tabs/windows and are comfortable with code, you can achieve this by altering one of the theme’s tempalte files: the “header-functions.php”, found in the theme root; line 242 should be changed to add a target=”_blank” declaration to the < a > element found in the string.
Sincerely,
Andrii / Satori Studio
