no, none at all. which is why I am so confused. it all works ok when the first box is a multi select box, the second box is a drop down and the third one is a multi select box, but not when all three are multi select boxes as I require.
In the scenario above, when I select multiple categories in the first multi select box, the next drop down gets dynamically populated with all the subcategories related to all the categories I multi selected in the first box. And when I select a single selection from that second drop down (this is all I can do with the drop down anyway) the third multi select box get populated with third level sub-sub categories related to the single selection from the second drop down.
So when I change the second drop down to a multi select so all three are multi select boxes, thats when the second and third boxes break and all the values from the lists that feed the second box populate the second multi select box immediately and the same with the third multi select box from the third list. I am looking the multi select box to be blank at first and start to dynamically populate with additional data the more items from the previous multi selectable box are selected.
Its almost as if it only works one level down as long as the previous box is always a drop down box vs a multi select box feeding another multi select box.
I hope I am making sense, I'm new to this, and I haven't seen this used in the way I am trying to get it to work.
Thanks again
