Range Slider Filter Definition

KNIME Quick Form Nodes version 3.7.1.v201901281201 by KNIME AG, Zurich, Switzerland

A slider which can be used to trigger interactive filter events in a layout of views (e.g. the WebPortal). The node appends a filter definition to the table spec.

Only view nodes downstream of this node can receive interactive filter events.

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.
