Hey @codecrazy, when using register you need to make sure you pass a unique one, maybe by using selectedSocialMedia.map 🤔 you can do ...register(`username.${index}`) or it will be better to use something else than index like you have id, maybe that? 🤔

but how it will bind the value coming from server for my understanding register must use the same object name also, there will be no id if the input is not set

What is the shape of the data coming from the server, when these fields are multiple?

its like { "companySocialMedia": [{ "id" "username":"", "type":"" }] }

Looks like the data is not accessible just with username. Its like companySocialMedia.${index}.username when you pass the same name parameter (first one) to register, having same values is the expected behavior since this is how react-hook-form distinguishes them 😅

is the word index a reserved word or i should get the index from the map ?

Not reserved, you should get that from the map or someway else. Like, its companySocialMedia.0.username for the first and so on. Please let me know if this works and if there's anything we can do to help 🙏
