BTW:
For example,
I want to create a Block, where you can choose if this will be the class container or container-fluid (true/false-field).
After this, you can Add your Colums, 1-12 and take settings, like wich classes you need for Mobile tablet and desktop. And of course Inside of thos Columns, the Content.
SO I want to create a fully neasted Blocks-Structure.
