Expand Panel on Hover

Menu 1

To programmatically change which event(s) open panels after initial setup:
$("selector").accordion("option", "event", "desiredEvent1 desiredEvent2");

Menu 2

The panels in this menu immediately expand upon mousing over their header. This can result in a poor user experience as accidentally mousing over headers instantly expands the new panel. hoverintent is suggested to avoid this issue as it puts a delay on activation by checking mouse velocity. An example with hoverintent can be found here.

Code

Note: hoverintent is more user friendly than mouseover.
      An example using hoverintent can be found -here-

                It is coded directly below an h element which jQuery's
                accordion method turns into the header you see above this content.
