As subjct says; is that possible?
Topic on Talk:Structured Discussions
If I understand correctly, you want to link to an equivalent of "§ion=new" ? That feature is planned, at phab:T59989.
What do you want?
- phab:T59989 asks for Flow boards to respond to an API request to add the wikitext of a new section. You can't link to that, it's the kind of thing a bot does.
- If you're asking for the equivalent of the [Add topic] tab on talk pages, Flow pages could respond to the same
?action=edit§ion=new
in the query string by focusing input in the "Start a new topic" input field. - If you just want a link that scrolls to the "Start a new topic" input field, that field doesn't have an id tag so a link could target e.g. #flow-new-topic. Since there's only one of these forms this seems reasonable (and easy).
- If you want to have a link that opens up the new topic form and pre-fills it with e.g. "Another great suggestion...", then it's doable in JavaScript (
$('.flow-newtopic-form .mw-ui-input').focus()
...) and if there's a good use case for it then Flow could support query string parameters that trigger this. - There's no way to know what the UUID of a new topic will be, it varies with time. So you can't write "Go see my [[Topic:S9ftya9qaez67kjo | Genius Idea]] until you add the new topic (and then copy its permalink).
It turns out that linking to https://www.mediawiki.org/wiki/Talk:Sandbox?action=new-topic might be what you want. You get a standalone form to add a topic (see result). This query string isn't officially supported; it's a side effect of every Flow action being permitted from the query string. So even if it's possible to improve this behavior it seems low priority.
actually the action=new-topic is officially supported, its part of the no-js compatibility.
probably only if you can guess this cryptic and user-unfriendly mumbo-jumbo in the url ;)
