Customizable arrow images
COOLjsMenu Professional allows you to define custom arrow images for any node. This can be done like in the code below:
{code:"Item 1", format:{arrow:"img/arr1.gif", oarrow:"img/arr1_o.gif", arrsize:[7,10]}
"arrow" field contains path to regular arrow image, "oarrow" points to image for rollover, and "arrsize" is the size of the images.
