Create a custom metadata type for your ComponentConfigGroup. I acknowledge that this is not the same as the nice interface you're looking for. If you've seen John Belo's Advanced Lightning Apps webinar he suggests a pattern that might help you though. That said, the use case is clear and obviously useful to a lot of people. You're right that this isn't supported yet, and there's no public scheduled roadmap for this (). If possible (which seems unlikely, but I haven't given up yet) I just need a simple example, the rest I can do on my own. Don't want to wait on Salesforce providing all that for me) In the meantime I figured dozens of meaningful missing usecases like better Tabs, better and more flexible Layouts and nested sub-Layouts all kinds of Panels and so on. The content needs to be designable in the App Builder. I need to create collapsible sections which can also be made invisible by conditions. Is there any example with source code or detailed documentation on how to create a Lightning Component, which acts as a container for sub components in the Lightning App Builder? for which release this feature is targeted?.what is the correct name of that feature? (it might be called or related to the terms 'placeholders' or 'regions' but this is unsure, and more feedback is required).Can we create a container component like that?

I'm looking for something like the standard Tabs component. Are Container components usable in the Lightning App Builder where I can put child components on it via point-and-click possible at all?
