Hi! I looking into re-useable content modules. I wish to be able to create a content module to a "folder" in the content tree. Then on a page I can mix between content modules and content references, that refereres to a content module in the "folder". With this, I would be able to have a shared module, that could be added to multiple pages, but be maintained in one place. However sinces content modules are registered as Element Type. They are not able to be created in the tree structure. Is there anyone who have done something like this?

If you can wait, it will probably be possible in v14 or v15 (June or December 2024)

Not entirely sure what you mean, but I think I do. We have a site with a Data folder where you can create 'reuseable blocks' In the block grid, there is a 'reuseable block picker' where you make a reference to that block. In the doctypes we have this BlockEditor -> Accordion block ReuseableBLocks -> Reuseable Accordion Block And the reusable accordion block, has a composition of the Accordion block
