www.uwosh.edu shows WordPress-Data.
The challenge is to select the n-item of the “posts” array.
This is possible with the pro-Version by some twig-template-code: (e. g. n=3)
[jsoncontentimporterpro url=”http://www.uwosh.edu/today/api/get_tag_posts/?tag_slug=cols” parser=”twig”]
{{posts[3].title}}:
{{posts[3].content}}
