Now that I think about it, I’m not sure you can have a text input as part of a Data Viewer List (DVL). Each label in a DVL is either static or dynamic. If static, all rows of the DVL have the same text. If dynamic, all rows are synced to the data in the data source.
So for a text input, I think it also has to be static or dynamic. So typing in a value would essentially make it a static component, copied to all rows of the DVL. That’s my guess, anyway.
