SignatureAPI now supports two additional place types for capturing data during the signing ceremony: boxed_text_input and dropdown. Both are available in envelopes with sequential signing, and both integrate with the existing capture_as mechanism so the values land in the envelope’s captures object.
Boxed text input
A boxed_text_input place renders as a row of individual character boxes. Set box_count to match the expected length, for example 6 for a verification code, 4 for the last digits of an SSN, or 5 for a ZIP code. Each box accepts a single character, which makes the field self-documenting and reduces input errors.
Use hint for a tooltip and prompt for placeholder text inside the first box. The field supports required and optional requirements, and you can tune width, height, and font_size to fit your document layout.
Dropdown
A dropdown place lets recipients pick one option from a list. Provide your own options as an array of {label, value} objects, or reference a predefined set such as us_states_names, us_states_2_letter_codes, world_countries_names, or the ISO country code variants. Set default to pre-select an option, and use behavior to force select or combobox rendering instead of the default auto mode, which switches to a searchable combobox above ten options.
Both place types work with placeholders and fixed positions, so they drop into existing documents the same way signature or text input places do. See the boxed text input docs and dropdown docs for the full attribute list.
