Slider Input (legacy)

This node is part of the legacy Quick Form nodes and will be deprecated soon. The replacement for this node can be found in the configuration/widget nodes. For more information on these new nodes see this blog post.

Outputs a double-precision floating point flow variable with a given number value. The value can also be controlled by a slider in the view or on the WebPortal.

The node supports custom CSS styling. You can simply put CSS rules into a single string and set it as a flow variable 'customCSS' in the node configuration dialog. You will find the list of available classes and their description on our documentation page.

Values: Draw labels and major ticks at positions of the actual values. Use the Values field to specify the values as a comma separated list of numbers.
