Accordion

class Accordion<T>(val visualizer: ItemVisualizer<T, AccordionItem>, val sectionVisualizer: ItemVisualizer<T, AccordionItem>, expansionModel: ExpansionModel = SingleItemExpansionModel(), item: T, remaining: T) : View, Iterable<T> (source)

A container that manages a list of items, each within a section that may be expanded or collapsed. This class delegates all rendering and configuration to its AccordionBehavior, which allows a high degree of flexibility regarding display and behavior.

Parameters

visualizer

to display each item

sectionVisualizer

to display the heading for each item

item

the first item in the list

remaining

items in the lest

Constructors

constructor(visualizer: ItemVisualizer<T, AccordionItem>, sectionVisualizer: ItemVisualizer<T, AccordionItem>, expansionModel: ExpansionModel = SingleItemExpansionModel(), item: T, vararg remaining: T)

Types
