Single Selection (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.

Allows selecting single value from a list of String which is returned as a String flow variable. The value can also be controlled from a QuickForm (KNIME 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.
