Question types

This page is the index of the question types, written by hand. A per-type reference, generated from the builder’s own list of types and options, will sit beside it. Until then the options below are the labels in the builder.

A Person question on a form anyone can open must have at least one group in Limit the choices to these groups, or the respondent could search everyone in your Foldr. On a form filled in stages, this applies only to questions filled at the first stage. A Person question filled at a later stage is answered by a signed-in user the form was passed to, so it needs no group limit. A Choose a file in Foldr respondent can only pick files they are allowed to open. Programs, scripts and web pages are never accepted as uploads.
Choice options from a field
Section titled “Choice options from a field”A Choice question that has Save answer to field set to a field with allowed values shows Use the field’s allowed values. Switch it on and the options are that field’s current allowed values on the form’s destination share. Foldr reads them each time the form opens, so a change to the field’s list reaches the form without publishing again.
The builder shows the list read-only, labelled From and the field’s name, in the question’s settings, on its card in the canvas and in Preview. Edit the list on the share, not in the form.
If the field loses its list, or the question stops saving to that field, the question’s own options apply, and the builder says so.
Every Choice answer must be one of the question’s option values, whether the options are its own or the field’s. Anything else is refused with Choose from the list. With several answers allowed, each one is checked.
Hidden value
Section titled “Hidden value”Never put a credential in a hidden value. The expression and the field it fills can be seen in the page’s data. Its value is worked out again on the server when the response is saved.
A Table question collects repeating rows. Each column has a Label, Type, Key and the options for that type. The column types include text, number, choice, yes/no and lookup. A lookup column looks up per row as the person types.
- Show total on a number column totals it under the table.
- Computed value (optional) makes a read-only column worked out per row from other columns by key:
row.miles * row.rate. - Save to (multi-value field) writes the column to a custom field that holds several values.
- Minimum rows, Maximum rows and Add-row button label set the limits and the button.
