If you have more than one toggle, make sure they all have a different id. :)

I've used this recipe several times, and I love it.  It works very well.  When I used it with (:panelist:) for quizzes, I made sure to use a variable from the page (say $Name) as the index.

Example of a quiz at work, entirely PmWiki driven -- each quiz's info is stored in data pages elsewhere on the site, they have categories and are pulled into various pages of the website...  http://bte18.com/Main/GolfingBasics  So you can see the different calls to the toggle javascript code on the HTML end here.

It's a combo of PmWiki and Javascript at work here.  :)

Try the same line in the toggle.php I got from the cookbook (years ago):
$HTMLFooterFmt[] = "<script type=\"text/javascript\">document.getElementById(\"{$id}\").style.display = '{$style}';</script>";

The moment that you name it ['toggle'] it will only make one entry in $HTMLFooterFmt.  with the [] it will just append them all to the array with numbered indexes.

If you want them indexed "toggle" then yes they need unique $id appended to 'toggle" so each index is unique... which is exactly what you said worked.
