Is WebComponent a Container for other Elements (low prio)

[Jochen Kühner]

We should also have a configuration to tell if a WebComponent is a container for other elements (maybe a array of querySelectors wich define possible elements)

[Jochen Kühner]

This is needed for a good designer experience, so I know if I could drag other components into

[Pascal Schilp]

How is this different from slots?

[Jochen Kühner]

Not every custom element uses slots

[Pascal Schilp]

Then im not sure what you mean. Can you provide some more information/context and some code examples, and a proposal of what you'd like to happen in the schema?

[Jochen Kühner]

Okay, maybe we also could use the the empty slot.
But then the empty slot is mandatory, means if it is not there the element is not allowed to have children

[Jochen Kühner]

or we do something like this
uses #46

   {
        name: "",
        allowedChildren: [":not(*)"]
    }
