line numbers and sorting in a portal
I have a portal on a form that fills up as I create new records on the form, I would like to have each record create a line number for it's entry in the portal, the position the line is in on the portal is significant to the way i want to see the data, however if I want to slip a line in between other lines on the portal so I can rearrange the order, I would like to change the line number of that line so it goes in it's place and then all the other above it automatically change there numbers to suit. (like how the tabbed order works)
I have tried a few things, any ideas?
or perhaps a drag and drop methods, so that I can grab a line and drop it where I want?
