I would like to configure the a repeater field to automatically populate it’s rows based on the value of another field. I’ve mocked this up in the attached screenshot. “Groups” is a multi-select where the user would choose taxonomy terms, once selected I would then like the “Group Specs” sub-repeater to populate with a set of rows which correspond to the terms selected.
Do you have any advice on how I could accomplish this? Thanks for the help.

Looks like my IMG link had stopped working. I’ve updated parent post with correct IMG embed.
Anyone have any experience or advice on how this could be accomplished?
