Drop-Down List

A dropdown list lets the user pick one or several alternatives from a fixed set of alternatives.

Single Choice

To restrict the user to picking a single alternative in a drop-down list, use the option input.

def formFieldSet = api.createConfiguratorEntry()

formFieldSet.inputs = [
    api.inputBuilderFactory()
        .createOptionEntry('option').setOptions('A'..'E')
        .buildContextParameter()
]

return formFieldSet

api.inputBuilderFactory()
        .createOptionEntry('option').setOptions('A'..'E')
        .getInput()

processor.addOrUpdateInput(                 //❶
        'ROOT',
        api.inputBuilderFactory()
                .createOptionEntry('option').setOptions('A'..'E')
                .buildMap()
)

❶ the processor can be one of the quoteProcessor, cProcessor, etc., which references subclasses of the CalculableLineItemCollectionBuilder

Multiple Choice

To allow the user to pick an arbitrary number of alternatives from a drop-down list, use the options entry.

In the examples, note the s at the end of options. This is what distinguishes the multiple choice drop-down from the single-choice drop-down.

Data Source Dimensions

A common use case is when the end user should select a value from a Data Source. For example, the user should be allowed to pick one of the years for which there is data.
