conditionally format similar portal rows
I'd like to be able to conditionally format rows of a portal that share a common field but can't figure out a way to do it. I can use a date field that remains the same for rows in the same 'group'.
Ideally I'd like a visual link, such as a background colour on a field, that changes each time my date field changes.
So, how do I map a date to a colour that can be used in a conditional formatting arangement ?
thanks for reading.
