We use Atlassian JIRA here and enable lookup UI on our ListView macro
Live DEMO below:
We use ListView with custom body layout, like this:
The service we use is Atlassian JIRA and it is defined in ConfiDoc configurations like this:
Very simple, no auth and uses just one parameter [KEY]
We use it with ConfiDoc's ListView macro
We have also enabled default lookup UI (with a bit of customizations over the default texts and labels)
And the result you can see on the top of this page. Welcome to ConfiDoc!
