When adding and employee, under Employee info there is the option to add Position, Twitter, Google Plus, and Facebook but not Linkedin.
Using this post’s instructions (https://athemes.com/forums/topic/link-and-icon-for-linkedin/#post-138629) I was able to perform the following steps:
Toolset > Dashboard > Employees > Employee info > Add New Field - add Linkedin.
Now Linkedin and a URL field are listed under Employee info, however, entering a Linkedin URL (or any URL) does not display the Linkedin icon with link on the live site.
The other post was way too vague about registering, unregistering and requiring. The links about each only explained about Wordpress native widgets, but not parent theme widgets. From what I can tell, what’s needed is which files to edit and code to use to unregister (and which widget to unregister), register (and where to name the new widget something different), and lastly which file to edit to and code to add to require the new widget. I hope this makes sense. Thanks!
