Some of a note sections (text under headings), e.g., “Used abbreviations”, are expected to be rendered collapsed/folded when a note is opened in the “View” mode.
While callouts can be marked with “-” and “+” characters (e.g., “> [!INFO]- Title” or “> [!INFO]+ Title”) to render them as collapsed/collapsable, this feature is missing for headers.
This need comes from use cases when a collapsed callout cannot be used.
E.g., a list of use abbreviations like the following won’t allow redirection when following the link:
> [!INFO]- Used abbreviations > - Term1: Definition1 ^Term1 > - Term2: Definition2 ^Term2 See [[#^Term1|the first term definition]].
In the above case, only placing the list outside the callout will create functional links.
Similarly, some headings like “Introduction”, “Foreword”, or “Acknowledgement”, etc. could be initially collapsed/folded when opening the note.
To introduce a new syntax, e.g., “##-”, “##–”, “##+-” to denote:
“##-”: a section should be collapsed on page open. All its subsections (nested headings) should be open. Equivalent to optional “##-+” syntax;
“##–”: a section and all its subsections (nested headings) should be collapsed on page open.
“##+-”: show subsection text, but collapse all of its subsections
“##-+”: similar to the above “##-”
“##+”: similar to plain “##”
“##++”: similar to plain “##”
Additionally, it would be nice if block references (^block-id), checkboxes and tasks could also work even when inside the callouts.
Attempting to put collapsed callouts under the heading.
## Acknowledgements > [!INFO]- Acknowledgements > Content that is not expected to be immediately accessible when opening the page. > > Cannot use links to blocks inside the callout. ^useless
