I want to show all properties of all subtrees while folding all of them is the default option but I can't find a option to this.
I suspect the the
outline-* set of commands may accomplish what you are looking for. They do not consider property drawers when unfolding an outline. In fact,
C-u C-u C-u TAB in org-mode (
org-cycle) actually calls
outline-show-all. If you don't want property drawers to be collapsed when folding headings you could bind TAB to
outline-toggle-children instead of
Old post I know, but if someone is interested check org-mode manual section 7: Properties and columns
