Wrapping sections in html not possible

Wrapping sections in html not possible

[Henry Hirsch]

Hello,

When the following code snippet is exported to html the 
jumbotron section is not wrapped in the jumbotron class but 
the jumbotron div is in another section and the closing div
is in the content of my jumbotron.

* Another Section
#+BEGIN_HTML
<div class="jumbotron">
#+END_HTML
* content of my jumbotron
This text is all about my jumbotron
#+BEGIN_HTML
</div>
#+END_HTML

* Another Section

So how can org mode support wrapping sections in html?
Especially for more complex cases where a section or
multiple sections will be wrapped in multiple divs.

I am using macros extensively and a workaround so far
is to not use org-modes sections but use a macro like
#+MACRO: heading #+HTML: <h2>$1</h2>
to create headlines. Which works but is unsatisfactory
for obvious reasons.

I am very interested in your thoughts. 

Regards
Henry

You can do this with an export filter or filters.  See the "Advanced
Configuration" section in the "Exporting" chapter of the manual.

Here is a simple example to get you started:
#+BEGIN_SRC elisp
(defun my-html-headline-wrap-filter (text backend info)
  "Wrap headlines in div.jumbotron during export."
  (when (org-export-derived-backend-p backend 'html)
    (concat "<div class=\"jumbotron\">" text "</div>")))

(add-to-list 'org-export-filter-headline-functions
	     'my-html-headline-wrap-filter)
#+END_SRC

As written, this will wrap *all* sections (including their headline) in
divs with the jumbotron class during HTML export.  You probably want to
do this for just some headlines, in just some documents.  So, you'll
need to add a test in my-html-headline-wrap-filter so that it only wraps
the relevant headlines, and leaves others unchanged.  Perhaps you can do
this based on the title of the headline, or the presence of some tag or
property.  If you need help with this, just ask!
 
Best,
Richard

Hello Richard,

Puneeth Chaganti created https://github.com/GlPortal/glportal_website/blob/master/plugins/orgmode/init.el (L 111-128).
Which works good but sadly it is not possible to use macros inside of the org source blocks.

We are currently looking for a solution.
