Like the title says. There are other extensions that do something similar: WikidataPageBanner, VisualEditor and Flow.
For example $wgGeoCrumbsAvailableNamespaces = (NS_Book; NS_Guide)
In spanish: GeoCrumbs debe poderse configurar en otros espacios de nombres como el espacio de nombres Guía o Info bajo la configuración adecuada.
This task sounds like a support question ("How can I do...?") for https://www.mediawiki.org/wiki/Extension_talk:GeoCrumbs or https://www.mediawiki.org/wiki/Project:Support_desk but not like a bug report or feature request? :)
If I understand T47665 correctly the current behavior is intentional.
Which MediaWiki version is this about? Which extension version is this about? Also see https://mediawiki.org/wiki/How_to_report_a_bug - thanks!
@Aklapper Yeah, it's a support question hehe. Sorry, it's the first time I've opened a thread here. As I didn't know where to ask because the discussion page is very abandoned and it wasn't clear to me who the authors were. I decided to ask in Phabricator.
MediaWiki version is 1.31.0 (59f789d).
GeoCrumbs extension version is 2.0.0 (f d7e115).
The only temporary solution is to create a redirection (List:Example to Example) and in List:TestArticle add {{Isin|List:Example}} to make it work.
@Hispano76: Nothing, see the previous comments in this task. :) I'm also closing this task as invalid, as it is not a bug report or feature request.
@Hispano76: I don't see a bug... If this is a feature request, feel free to reset the task status to "open" and rephrase the task summary to something like Allowing having GeoCrumbs enabled in other name spaces with a tag similar to wmgVisualEditorAvailableNamespaces or such, via Edit Task in the upper right corner. Thanks! :)
@Hispano76: No (and there is no need to ask). You or anyone else is welcome to work on fixing this task, if you/they want to see this task fixed. Thanks!
I found a forced solution to solve that problem: {{#if:{{{1}}}| {{#isin:{{ns:0}}:{{{1}}} }} }}. In a namespace called "Help" you will still link to an article in the main space/articles
