How do I keep Hide / Show Region open

Question

Hi,
I have a page with one region based on a hide/show template. The current behaviour on a page submit is that the region always hides.
I'd like it so that if the user opens the region that it will remain open after the page refreshes.
Thanks,
Brian

This is a hack so I wouldn't count on it, but it worked for me (in variation, I needed a bit different thing). And, remind you, it only holds one of them open for a page (my logic is, that when they are hidden no more than one should be open at once).
1) the page should have an item that holds the information - I'll call it OPEN_REGION. I am knowingly ignoring the usual Pn_ naming convention so all pages with Hide / Show regions could have their own OPEN_REGION but the name could still be uniquely referenced in javascript. It should be a hidden variable in the topmost region in the template (which must not be one of those enhanced HIde/Show regions).
2) make a new javascript function to set the item and submit page. Be careful to make sure you use valid variables or javascript errors display when no OPEN_REGION item is on the page (for example).
function myHideShow ( region )
if (document.getElementById('OPEN_REGION'))
if ( document.getElementById('OPEN_REGION').value != region )
document.getElementById('OPEN_REGION').value = region;
}else{
document.getElementById('OPEN_REGION').value = '';
doSubmit();
2) edit the region template. Set it to call your own function.
Where it sais:
href="javascript:hideShow('region#REGION_SEQUENCE_ID#','shIMG#REGION_SEQUENCE_ID#','#IMAGE_PREFIX#jtfuhide.gif','#IMAGE_PREFIX#jtfushow.gif');"
make it (set the page item to the region sequence number):
href="javascript:myHideShow('#REGION_SEQUENCE_ID#');"
3) edit your page template, in the footer add the opening of the region. Be careful to make sure you use valid variables or javascript errors display when no OPEN_REGION item is on the page (for example).
<script>
if (document.getElementById('OPEN_REGION'))
if (document.getElementById('OPEN_REGION').value != '')
theRegion = document.getElementById('OPEN_REGION').value;
hideShow('region'+theRegion, 'shIMG'+theRegion, '#IMAGE_PREFIX#jtfuhide.gif', '#IMAGE_PREFIX#jtfushow.gif');
</script>
That should do it, but be aware, that I am not in Oracle team, just a simple programmer trying to find my own solutions and Javascript has helped me here sometimes.
For example, try to use #TITLE# substitution string in BODY part of the Page Template...
