We have released the ability for senders to add radio buttons and drop down lists to documents within a signature request or document template.
Senders can now add groups of radio buttons to documents, which require signers to select exactly one radio button out of the group. Radio button groups require a minimum of two radio buttons per group.
Additionally, senders can now add drop down lists to documents, which allow signers to select a single option out of a list of options.
