Key-Value Pair List custom field
Anyone already build a custom field that can do a list of arbitrary key-value pairs?
I imagine it would be persisted as a json associative array string in the backend; render with a list of textbox pairs with the ability to add/remove individual items. Reorder would be nice but not impossible.
I'm not a KO guy but this doesn't seem particularly difficult to me; thought I'd ask around before building.
