Main question:
Are Container components usable in the Lightning App Builder where I can put child components on it via point-and-click possible at all?
I'm looking for something like the standard Tabs component. Can we create a container component like that?
If this is currently not supported:
- is this on the roadmap?
- 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)
- for which release this feature is targeted?
- is there a pilot program?
If this is currently supported:
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?
Why do I need this?
I need to create collapsible sections which can also be made invisible by conditions. The content needs to be designable in the App Builder. (Edit: this was only my first need. 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. Don't want to wait on Salesforce providing all that for me)
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.
