Atomik, V. 9.4.1. I cannot use containers in composer templates and use “setup on child pages”. On save, nothing there.
Now that @VisualNotes found how to use predefined css classes for containers, it would great to use containers in composer templates.
There is a github issue on this, which you can add your thoughts to:
opened 11:46AM - 10 Apr 25 UTC
Type:Enhancement
Affects:Content Creators
Product Areas:Page Defaults
Enhancement:Level Of Effort:3
### Affected Version of Concrete CMS
9.x
### Description
Concrete version 9.3… .9
When editing a page type default, specifically adding a new block, I always use the “setup on child pages” function to propagate this new addition to the children using that page type.
However, when a newly added block is inside a container, like so:

this function does nothing.
It seems Concrete ignores the container structure when setting the blocks up on the child pages, or rather ignores blocks within them and sets up nothing.
### How to reproduce
1. Create a page type default and create a child page using that page type.
2. Go back to edit the page type default, add a new container somewhere in the template and insert a block into the container.
3. On that block click on "Setup on child pages".
4. The block never appears on the child.
### Possible Solution
Make sure that if a new block is added to a page type default and the "Setup on child pages" is called, the block is copied over to the children including a container it sits within.
Alternatively, add a "Setup to child pages" to the container level, so the whole container could be pushed to the children, including all its blocks.
### Additional Context

Thanks John for mentioning the already existing Github issue.
No thoughts to add, - it’s just not working.
