Limited places per option, dependent dropdowns and options from a list

Cap how many people can pick each option (seats, time slots, sizes), show options that depend on an earlier answer (country → city), and keep dropdowns in sync with a CSV, SharePoint list, Excel table or Google Sheet.

SnagBane choice questions can do three things most form builders can't: limit the places per option, show options that depend on an earlier answer, and keep their options in sync with a list maintained elsewhere. Places and dependent lists are on every plan; options from SharePoint, Excel and Google Sheets need Business.

Places per option

Turn on Limit places per option on a single-choice, multiple-choice or dropdown question and type how many people can choose each option — seats in a session, time slots, T-shirt sizes.

  • A full option shows as Full and can't be chosen.
  • The server checks again when the form is sent, so two people can't take the last place.
  • Rejected requests give their place back; editing a response keeps its place.
  • Show places left shows “3 places left”; the summary shows “12 of 20 places taken”.

Dependent lists

Show options depending on picks an earlier choice, dropdown or yes/no question; next to each option you choose the answer it belongs to.

Equipment: Laptop14", 16"

Respondents see only the matching options, a changed answer unticks what no longer fits, and the server accepts only matching options.

Pick the column with the names — and, for dependent lists, the column with the answer each belongs to, and places. SnagBane refreshes linked lists every hour; a name that disappears can no longer be chosen, while earlier answers keep it.

Also on choice questions

  • “Other” with a text box — the typed answer shows in results; summaries count it as Other.
  • Shuffle the options against order bias in surveys; Other stays last.

Frequently asked questions

Can a workshop sign-up close options automatically when full?

Yes — that's exactly what places per option do.

Can our cost centres come from a SharePoint list?

Yes, with Business: link the dropdown to the list and it stays up to date.
