Single Selection Widget

Allows selecting a single value from a list of strings in an encapsulating component's view. The selected value is returned as a string flow variable.

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.
