Thank you for contacting us, our team is happy to answer any questions you have about working with BoldGrid on your website.
The way to add social media icons to your menus is to use the Custom Link option in the list of available items. BoldGrid themes will automatically detect which URL is used for the link and supply the appropriate social media icon based on that.
Our theme framework is able to determine the appropriate icon for most of the major social media sites, but occasionally there are some it cannot find. We also have some documentation on how to add your own custom icons for sites the framework can’t detect correctly.
I hope this helps you get your social media menus working as expected and please let us know if there is anything else that we can do to assist you.
