I have a rather lengthy multi-excerpt and I would like it to be an expand so that only the header is visible by default and the user can expand it for the details if desired. But whenever I try to insert an expand into my multi-excerpt, it adds a new block beneath the multi-excerpt. Is it not possible to include an expand inside a multi-excerpt?
If not, any advice on achieving my goal of collapsed default content in a multi-excerpt?
Thanks!
