This sample uses multiple Swipe widgets to create an seemingly infinite scroll between different Educational Attainment layers in Mexico.

How it works

For each layer loaded from a WebMap, a swipe widget is created, and the layer is added to the trailingLayers.

// create a swipe widget for each layer
swipes = layers.map(function(layer) {
  return new Swipe({
    view: view,
    disabled: false,
    position: 100,
    direction: "vertical",
    trailingLayers: [layer],
    visibleElements: {
      handle: false,
      divider: true
    }
  });
});

When the user scrolls through the app, the leadingLayers and trailingLayers update as the Swipe widget's position changes to achieve the infinite scroll effect.

// To achieve this infinite scroll effect we need to swap the layers:
//   The layer starts at the bottom, the divider goes up.
//   Then the next layer starts to show up, so we put back the divider at the bottom and swap the layers.
if (position < 0 && swipe.trailingLayers.length) {
  swipe.leadingLayers.addMany(swipe.trailingLayers);
  swipe.trailingLayers.removeAll();
} else if (position >= 0 && swipe.leadingLayers.length) {
  swipe.trailingLayers.addMany(swipe.leadingLayers);
  swipe.leadingLayers.removeAll();
}
