Relevant links:

specifically:

The structure of a notebook document looks something like:


<div id="cell_text_2" class="text_cell" title="">
   <h1>h1 heading</h1>
</div>
<script></script>
<div id="cell_outer_1" class="cell_visible"></div>
<div id="cell_outer_3" class="cell_visible"></div>
<div id="cell_text_5" class="text_cell" title="">
   <h1>another h1 heading</h1>
</div>

So (without restructuring the notebook html), you could use jquery to 
select the parent of the hi with class text_cell, then select all 
sibling divs until you got to the next div that had an h1 heading as a 
child.  Then just toggle all of those divs.  It's probably one line of 
jquery.

Somehow, you'd have to tag each hi with the appropriate javascript code. 
  This is probably doable from the text cell creation code (see the code 
that creates the <script> tag above; it is generated on the fly when a 
text cell is rendered from cell.py).  It's also probably doable from 
both the html insertion code in the main javascript code, or also from 
tinymce.
