Hey, I'm sorry if this is not the right channel for the following question. Can I create a custom body field / custom column field and insert a subrecord (for ex: address) into that? Thanks in advance

You can create a custom field with an input type of list and set the list type

@S Feld Thanks, but I was asking about something like address subrecord that opens up a dialog box where we can enter state, city and so on.

Perhaps with a client script calling a suitelet

Okay, can that be done by any standard means?

What's your use case @Joe Thomson?

@NickSuite Let's say that I need to duplicate an entity record in a custom record. How can I bring the address fields to this new custom record with minimal customization?

You will need another custom record for addresses. Then Create a child record for each of the address of that entity.
