I don't know if this is the right place to post this ...
When will this mudule be available for D7 ?
Marking as duplicate of #1551504: Create stable release of conditional_fields for 7.x. It seems like it's pretty close, and nearly as many people use the dev D7 version as use the stable D6 version.
