Hey stolle,
thanks for your explanation.
Foundation F6 CSS/SCSS was installed before. It works fine, without layout-problems. Also my own foundation nodeTypes works also fine (looked only on the layout) with nesting elements.
####But something is happen with the js-Button in the Inline-Editor.
Im quite sure, the js-Error is not triggered from foundation or CSS. I think it is because the nested nodeType. Something in js-Element is lost by nesting.
Reason to believe this: If I drag and drop the inner nodeType outside the wrapping nodeType -> no problem with button-action (of corse with layout 
) .
####Back inside the wrapping nodeType, the button has no function and the console shows the error. But Layout is back without deficit 
.
I will try your bootstrap-Grid-Package. Maybe (I’m quite sure) your Package will run with Inside-Edit-Button. So I could use it as Bolderplate for Foundation NodeType and Section NodeType. Would be great.
I would like to use Foundation F6, with his MobileFirst- and SCSS-Approach things. But who knows, maybe I swing back to Bootstrap.
