html - Is it possible to collapse/expand a DIV within an email? What clients support this?

Question

I have an alerting system that sends out alerts by email. I would like to include diagnostic information but only make it visible if the end user clicks a [+] button.

Is this possible to do in email? Can I do it without using Javascript and only CSS?

If it helps, most of my clients use Outlook, iPhones, or Blackberries

Answer 1

Most likely, not. JS has been disabled in a lot of clients, due to viruses and stuff.

A workaround might be to include a URL to the full error-page with all details, and edit your mail to only summarize the diagnostic information.

Also, you could try to see if you can use :hover CSS, to show the element with some nasty selectors... CSS3-style? http://www.campaignmonitor.com/css/
