I saw the following article about adding external links to list view.
crosstec.org/en/support/online-documenta...r-element-value.html
I had a field with fully formed website links in it and another with emails in it.
to make the website link clickable in list view you can put the following code in the item wrap code.
<a href="{value}">{value}</>
fair warning it has to be a complete web address including http:// or https://
for email you can use:
<a href="mailto:{value}">{value}</>
This may be stated somewhere else that I have missed or may be completely elementary but I thought perhaps someone else may search for it.
