I’ve been asking for this since day 1. In fact, I don’t think I’ve ever used getChildren because it’s useless without being able to limit results to a specific type of content. It’s best to just use content.query and then specify the path starts-with and contentTypes.
But I think sort: ‘_manualordervalue DESC’ only works with getChildren… not query, so since manual sort order is very important in this instance, I cannot use query. And thus the only workaround is to filter the result from getChildren
