I have an idea for a droplet that shows a jQuery tabbed field for multiple WYSIWYG sections. What I envision is this:
1. create the WB sections for all tabbed contents you need. Let's say you want to show info on 3 products. So you create 3 sections with content, that show up when you click on the tabs: Product 1, Product 2, Product 3.
2. use a droplet like [[ShowTabs?section=10,11,12&tabs=Product 1, Product 2, Product 3]]
And then the droplet adds all markup needed (of course you need jquery and the jquery call active, and css for the tabs). Maybe even extra class and id parameters can be added to the droplet, for extra styling options.
I think maybe http://www.websitebakers.com/pages/droplets/official-library/content/show-multiple-wysiwyg.php
may be a good starting point for this droplet.
For the tabs I think it's best to use some standard like http://jqueryui.com/demos/tabs/
To prevent the tabbed sections be visible on the page as regular sections as well, you can just set their end dates in the past. That way they don't show up, but they can still be called with a droplet.
I have tried to do this myself based on the ShowMultipleWYSIWYG droplet, but failed miserably. My coding knowledge is too minimal... But I have a feeling this won't be too difficult to do for some experienced WB coders...
