I wanted to convert it to global group so I could use the module in an email I already created in the content editor. But as you can see in the screenshot below, that action is greyed out. I am not using flexible columns, the social share is a copy (thus not the global module), and as far as I can tell we are on the latest version of design manager (thus no updates needed.)
Alternatively, if there is a better way to create the footer module so it is easily available to port into emails instead of designing an entire email template, I'm all ears.
I've searched the HS community forums but haven't found anything similar. Thanks. Development skills are beginner.
Thank you @Kevin-C for helping. Ultimately, I took the default HS footer module, added "Follow us on social" above and added some basic styling and was able to add it to my current email that I created from the content editor.
And by the way, in your method, you suggest creating a global email module, but isn't that not possible? (i.e. we can only use the global ones provided by HS or make copies of those ones?) Or were you suggesting creating a global group in a different template (a webpage for example) and then making it a global module that could be used in an email template?
