To the left of table of content entries you can click on an open/close icon to toggle the visibility of different levels of the table of contents.
The main use case covered by the expansion algorithm is as follows:
- the page starts with all nodes open to facilitate Ctrl + F queries
- if you click an open node, you close its direct branches to get a summarized overview of its contents
- you can then click it again to close the node itself
- clicking a closed node opens its entire subtree, after which you can summarize it again
The exact behaviour is:
- summarized: the clicked node is open and every direct child is either closed or has no children. Action: close the clicked node
- closed: the clicked node is not showing its children. Action: open the clicked node and all its descendants recursively
- any other open state, including a fully open or mixed subtree. Action: summarize it by closing every direct child that has children
The main cycle is therefore: summarized -> closed -> fully open -> summarized.
Clicking on the link from a header up to the table of contents also automatically opens up the node for you in case it had been previously closed manually.
