It is possible to create a widget container with WixBlocks?

Hello, it is possible to create a widget container with WixBlocks.
That is, when I use it in a page in another widget,
I can drop items into the container.
I haven’t found how to do it. Can anyone help me?
Thanks

Hi @cameleonmtl,

Welcome to the community! Can you provide a little bit more context as to what you’re trying to achieve?

This is my control. If I use this control afterwards in another widget, it is impossible to put (Attach) an element in the boxContent while it is a container. Is there an option or a way to do where it is impossible to have your own container?
