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.

Number of visible rows: A number of options visible in the List component without a vertical scroll bar. Changing this value will also affect the component's height. The setting is available only for List selection type.
