Hi mkdocs,

In large pages it would be really great some sections to be collapsable like https://squidfunk.github.io/mkdocs-material/reference/admonitions/ but whole standard section
The markdown syntax could be similar
??? ### "title"
contents
with the section title managed in the table of contents.

Would this possible ? I can help also to co-develop (i am not familiar with mkdocs but with underlying technos i am).

Thanks in advance.
