Hi,
I'd like to have collapsible source code blocks in my org document
exported to HTML. To collapse and restore I have used[1]. The library
requires a link (or a button) with appropirate properties. A link needs
to point (href) to a block and have additional custom data-toggle
property. On Debian9/Emacs 24/org-mode 8.x I was able to craft such
links by hand
#+HTML: <a class="btn" data-toggle="collapse" href="#code1">Show</a>
#+NAME: code1
#+BEGIN_SRC python
return 42
#+END_SRC
On Debian10/Emacs26/org-mode 9.1.9 src blocks with a NAME get
automatically generated id-s (org-export-get-reference) and I can see no
way to determine href in my HTML snippet. (ATTR_HTML before org-mode
link does not work as advertised in the manual either).
Is there any way to generate a link (or a button) for every code block
with matching href/id you can recommend?

Kind regards,

You want the equivalent of the LaTeX exporter's
,----[ C-h v org-latex-prefer-user-labels RET ]
| org-latex-prefer-user-labels is a variable defined in ‘ox-latex.el’.
| Its value is t
| Original value was nil
|
| You can customize this variable.
|
|
| This variable was introduced, or its default value was changed, in
| version 26.1 of Emacs.
|
| Documentation:
| Use user-provided labels instead of internal ones when non-nil.
|
| [...]
|
| For headlines that do not define the CUSTOM_ID property or
| elements without a NAME, Org will continue to use its default
| labeling scheme to generate labels and resolve links into proper
| references.
`----
I don't think the HTML exporter has anything similar but it should be
possible to implement...
