Piping is a feature that automatically transfers a respondent’s answers from one Choice (or Matrix) block into the next question. This allows you to show only the options that are actually relevant to the respondent — for example, the ones they selected earlier or the ones they did not select.
What is this used for?
- Clarifying choices
For example, first the respondent selects the brands they have used. In the next question, they need to rate only the selected brands — these options are inserted automatically.
- Exclusion scenarios (negative logic)
You can collect unselected options and, for example, ask: “Why have you not used these brands?”
- Dynamic matrices
In matrix questions, you can build rows only from the options that are relevant to a specific respondent.
- Reducing cognitive load
The respondent does not see unnecessary items → data quality improves.
- Working with custom “Other” answers
If a respondent enters their own option, it will also appear in the next question as a separate choice.
Who can use the “Piping” feature?
- Currently, the “Piping” feature is available only to participants who applied for beta testing.
Usage limitations
- The source for Piping must be a Choice block that:
- Comes before the block where the answers will be inserted.
- Has the setting “Allow multiple choice” enabled.
- You can substitute:
- Options in a Choice block.
- Rows in a Matrix block.
Functionality details and modes
- Two substitution modes:
- Collect all selected answers (i.e., answers that were chosen).
- Collect all unselected answers (i.e., answers that were not chosen, e.g., for building negative logic flows).
- You can use a block as a source even if it already uses Piping.
- “Other” answers are also included — the custom text input is passed to the next block as a separate option.
- The “None of the above” option is not inserted, but if using the “were not chosen” mode, all other possible options will be inserted.
- A block with Piping may be skipped if there are no options to insert (for example, if “None of the above” was selected).
- A block with Piping may become optional if only one answer option remains — in that case, the respondent can proceed without selecting anything.
