Unable to add components inside Custom Layout Container
Hello,
We are trying to create custom Layout Container(wcm/foundation/components/responsivegrid) component and allow some components to add inside it.
Below are the steps:
1. Created a new "Custom Layout Container" component and given it's superType as
sling:resourceSuperType="/libs/wcm/foundation/components/responsivegrid"
2. Added the policy in the template for this new Custom Layout Container to add components inside it.


The problem I'm facing is, after adding this new "Layout container" on a page, not able to add any other components inside it. It does not have any height (which ootb layout container has and "Drag Components here" is also not coming.

Has anyone experienced this issue?
Thankyou.
