Hi,
What I am trying to do is a pretty common UI convention - in that I will have 1 select that allows multiple selects - I will have an add and remove button and then I will have a second select (that also allows multiple selects). The first select will contain a superset of data - the second select is meant for the user to populate based on adding (and removing) data from the first select.
FirstOff, I am wondering if there is a link to some sample code to do this as it is so common.
Secondly, if there isn't - the parts I am finding tricky are the fact that they can add and remove multiple - and then when you add a value into the second subset select it needs to check that that value doesn't already exist - so it doesn't add it to the list twice.
Many Thanks - this is a very helpful site.
