crowd-slider - Amazon SageMaker


A bar with a sliding knob that allows a worker to select a value from a range of values by moving the knob. The slider makes it a great choice for settings that reflect intensity levels, such as volume, brightness, or color saturation.

The following is an example of a survey template that uses the <crowd-slider> element. Copy the following code and save it in a file with the extenion .html. Open the file in any browser to preview and interact with this template.

<script src=""></script> <crowd-form> <crowd-instructions link-text="View instructions" link-type="button"> <short-summary> <p>Provide a brief instruction here</p> </short-summary> <detailed-instructions> <h3>Provide more detailed instructions here</h3> <p>Include additional information</p> </detailed-instructions> <positive-example> <p>Provide an example of a good answer here</p> <p>Explain why it's a good answer</p> </positive-example> <negative-example> <p>Provide an example of a bad answer here</p> <p>Explain why it's a bad answer</p> </negative-example> </crowd-instructions> <div> <p>What is your favorite color for a bird?</p> <crowd-input name="favoriteColor" placeholder="example: pink" required></crowd-input> </div> <div> <p>Check this box if you like birds</p> <crowd-checkbox name="likeBirds" checked="true" required></crowd-checkbox> </div> <div> <p>On a scale of 1-10, how much do you like birds?</p> <crowd-slider name="howMuch" min="1" max="10" step="1" pin="true" required></crowd-slider> </div> <div> <p>Write a short essay describing your favorite bird</p> <crowd-text-area name="essay" rows="4" placeholder="Lorem ipsum..." required></crowd-text-area> </div> </crowd-form>


The following attributes are supported by this element.


A Boolean switch that, if present, displays the slider as disabled.


A Boolean switch that, if present, displays an up/down button that can be chosen to select the value.

Selecting the value via the up/down button is an alternative to selecting the value by moving the knob on the slider. The knob on the slider will move synchronously with the up/down button choices.


A number that specifies the maximum value on the slider.


A number that specifies the minimum value on the slider.


A string that is used to identify the answer submitted by the worker. This value will match a key in the JSON object that specifies the answer.


A Boolean switch that, if present, displays the current value above the knob as the knob is moved.


A Boolean switch that, if present, requires the worker to provide input.


When used with a crowd-slider-secondary-color CSS attribute, the progress bar is colored to the point represented by the secondary-progress. For example, if this was representing the progress on a streaming video, the value would represent where the viewer was in the video timeline. The secondary-progress value would represent the point on the timeline to which the video had buffered.


A number that specifies the difference between selectable values on the slider.


A preset that becomes the default if the worker does not provide input.
