Hey Dustin,
Fields accept HTML input, so you can add a link using HTML. You can read here about the
"a" tag which allows you to create a web link.
The simple explanation is, if you want to make something in your description a clickable link, you have to wrap it with "<a href='url'></a>" tags. So if you input the following into a field, for instance:
It will output as the following:
And when you click it, it will open up "
google.com". You can of course edit that tag to redirect to whatever URL your vendors website is.
Note: make sure you include 'target="_blank"' inside the a tag like I showed in the example, otherwise the link won't open.
Let me know if that helps.
