Highlight all zones

[Scott Rakestraw]

I have several dock zones on my page that all do not have borders or background colors.  When the user drags a dock I want to highlight all the dock zones so that the user can see all the possible places they can place the dock.  How do I go about implementing that?

"When the user drags a zone" ?? May be you want to say "When the user drags a dock" ?
