UIConditional

class UIConditional

extends UIRenderableController

Encapsulates content that is added/removed asynchronously based on the value of a (bound) property.

Note: Preset constructors for this class (see example) only accept one child component. To wrap multiple components, use multiple UIConditional constructors, or wrap child components in a UICell.

Example (preset)

UIConditional.with(
  { state: bind("showRegion") },
  UICell.with(
    UIRow.with(
      tl("Only rendered when state is true")
    )
  )
)
