Hello @evachang,

You can add the social links menu( Facebook / Twitter box ) in the header section of your website even in the free version of the Education Hub theme.

For this, you will first need to create a new “social” menu. Go to your Admin Dashboard > Appearance > Customize > Menus and click on “Add a Menu”. Enter a menu name and click “Create Menu”. Now click on “Add Items” > and then “Custom Links”. Enter your social links along with a label and click on “Add to Menu”. You can add multiple social links in the same way. Finally, in the same screen under “Menu Locations”, check “Social Menu” checkbox option and save & Publish your changes.

After creating and assigning social menu, you can toggle the display of the social icons in the header from Admin Dashboard > Appearance > Customize > Theme Options > Header Options > Show social icons checkbox.

Hope this helps,
Best Regards !!
