Set queryable source on Rendering Parameter Template field
问题 I have a Rendering Parameter template applied to a sublayout. It has a single Droptree field on it, and I want to set the Source of that field to a Sitecore query so I can limit the options available for that field. Source can be: query:./* or query:./ancestor-or-self::*[@@templatename='MyTemplate']/ The query just needs to grab items relative to the content item that we're on. This normally works with Droptree fields in the content editor. However I'm finding that the query isn't working
