**Note: This will not function, until the blocked tasks are resolved, too. A rough ETA for those is ~3-4 weeks hence (so, the week of December 14/21)** (it was prematurely announced in Tech/News, sorry)
See documentation for the `format` parameter, at:
* https://www.mediawiki.org/wiki/Help:TemplateData
* https://www.mediawiki.org/wiki/Extension:TemplateData
However, here are two examples of how to add the parameter, at beta cluster:

Original title: html2wt: new templates should display one parameter per line
I understand this was partly discussed in {T53175} (with suggestions about how to handle the issue), but whatever happened next didn't seem to affect this :)
If you check out the source of https://it.wikipedia.org/w/index.php?title=Utente:Elitre_(WMF)/Sandbox_VE&oldid=64531360 , you'll notice a couple of templates at the top. Those were added with VE, and are collapsed, whereas editors on it.wp would want those kind of templates (which are basically infoboxes) to always display one parameter per line, no matter what the length of the template is.
