I've created a very basic form that has 2 dropdown lists.
Each list contains the same entries:
<option value='1234:0'>Closed</option>
<option value='4567:2'>Open</option>
<option value='6857:1'>Dead</option>
<option value='9856:1'>Alive</option>
<option value='0000:0'>Other</option>
If an entry in dropdown 1 is selected, then that entry should be removed from dropdown 2
If a different entry is selected in dropdown 1, then that should be removed from dropdown 2 and the original entry returned to dropdown 2
if nothing is selected in dropdown 1, then all options should be shown in dropdown 2.
I've created a FIDDLE, showing how far I've got... it's not very far.
Can any one help with this ?
Thanks
