How the Slider block works

The Slider block lets respondents pick a number by dragging a handle along a scale, or pick a low-to-high range with two handles. Use it for budgets, amounts, percentages, or any question where a number on a scale feels more natural than typing one. It is free on all plans.

Add a Slider block

1. Open your form in the builder and add a new block

2. Choose Slider from the block picker

3. Type your question, then set the options in the right panel

4. Publish the form to make the slider live

Slider settings

All settings are in the right panel when the block is selected.

• Min and Max: the two ends of the scale. Defaults are 0 and 100.

• Step size: how far the handle jumps per move. A step of 5 on a 0 to 100 scale gives 0, 5, 10, and so on. Default is 1.

• Default value: where the handle sits when the respondent reaches the question. It is clamped between Min and Max and snapped to the nearest step.

• Prefix and Suffix: text shown before or after the number, for example $ or kg. Respondents see the formatted value update live as they drag.

• Thousand separator: comma, period, space, or none, so 1000 shows as 1,000 or 1.000 or 1 000.

Range mode (two handles)

Turn on Range mode (two handles) when you want a low and a high value, such as "What is your budget?" answered as $2,000 to $5,000. The block then shows two handles and two default fields, Default (low) and Default (high).

The answer is saved as a pair and shown as "low - high" everywhere: the Submissions table, CSV export, Google Sheets, webhooks, email notifications, and answer recall.

Required and skipping

A slider always carries a value once the respondent reaches it, so there is no required toggle. The default value is recorded as the answer if the respondent moves on without touching the handle.

Logic and calculations

Slider answers are numbers, so you can use every numeric condition in logic: equal to, greater than, less than, and so on. You can also use the value in calculations.

Summary

The Summary tab shows the average answer for each slider. In range mode it shows the average low and the average high separately, for example "Average: $2,400 – $5,100". Only submissions received after the block was added are counted.

Keyboard and touch

Respondents can drag the handle with a mouse or finger, or focus it and use the arrow keys to move one step at a time.
