How to show all contents of current subtree and fold all the other subtrees?

Question

When using org build subtree navigation functions to move around, I want to show all the content of current one recursively, and hide any other subtrees that having a higher or same level of the current one. How to achieve this ? Thanks !

Not quite sure if this is what you want, but here's a function that will show the current subtree (and its children) and fold all other headings to their top level:

(defun ess/org-show-just-me (&rest _)
  "Fold all other trees, then show entire current subtree."
  (interactive)
  (org-overview)
  (org-reveal)
  (org-show-subtree))

Now you can add advices for each command you want to use this function together with:

(advice-add 'org-forward-heading-same-level :after #'ess/org-show-just-me)
(advice-add 'org-backward-heading-same-level :after #'ess/org-show-just-me)

Another alternative is to use org-narrow-to-subtree to hide all other content than the current subtree. It is bound to C-x n s by default. To go back, use widen, bound to C-x n w. A great alternative is narrow-or-widen-dwim.

You could add widen followed by org-narrow-to-subtree to a function and create this as an advice in the same way as the example above.
