Multiple Selection Widget

Allows selecting multiple values from a list of strings in an encapsulating component's view. The selected values are returned as a data table and 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.

Options

Control

Label: A descriptive label that will be shown in the view.
Description: Some lines of description that will be shown in the view, for instance by means of a tooltip.

Selection Type: The type of the selection element. This can be either check boxes with a vertical or horizontal layout, a List or a Twinlist.
Possible Choices: The possible choices, each line is one possible value.
Default Values: Values selected by default.
Limit number of visible options: By default the List and Twinlist components adjust their height to display all possible choices without a scroll bar. If the setting is enabled, you will be able to limit the number of visible options in case you have too many of them. The setting is available only for List or Twinlist selection type.
Number of visible options: A number of options visible in the List or Twinlist component without a vertical scroll bar. Changing this value will also affect the component's height. Notice that for Twinlist the height cannot be less than the overall height of the control buttons in the middle. The setting is available only for List or Twinlist selection type.

Re-execution

Re-execution on widget value change: If selected, widget emits reactivity events that trigger the re-execution of downstream nodes in a component composite view when its value changes. It allows users to create interactive Data Apps and visualizations.
