In ReadTheOrg, display only the 1st level entry selected from the tableofcontents

[Julien Cubizolles]

Let's say I have an org file like

* A
** a
** b
* B
** c
** d

I'd like to display only

** a
** b

when I select *A from the table of contents. Is there a configuration option for that ?

Here's Jorge Paredes' answer:

It is not an issue relative to the theme. In your org file you only need to put:
`#+OPTIONS: toc:1 `

[Julien Cubizolles]

I don't think the toc options is enough to get the behaviour I'm looking for.

toc:1 will always display only the top-level entries:
*A
*B

Whereas I want to display the 2nd level entries of the currently selected 1st-level entry:

• a
• b
  displayed when I select *A
  and
• c
• d
  when I select *B
