To create a Infinite Scroll View in the Unity Editor, go to GameObject → UI → Infinite Scroll View.

Prepare ScrollItem prefab to be repeatedly displayed by infinite scroll.

public class SimpleInfiniteScrollItem : MonoBehaviour, IInfiniteScrollItem { /// <summary> /// ScrollItem enters display area and updates display item data. /// </summary> /// <param name="data"></param> public void UpdateItemData(object data) { if (!(data is float width)) return; gameObject.SetActive(true); if (!(gameObject.transform is RectTransform rectTransform)) return; rectTransform.sizeDelta = new Vector2(width, rectTransform.sizeDelta.y); } /// <summary> /// Hide ScrollItem because it has left the display area. /// </summary> public void Hide() { gameObject.SetActive(false); } }

Call InfiniteScrollRect.SetItemData to set the item data.

[RequireComponent(typeof(InfiniteScrollRect))] public class SimpleInfiniteScrollController : MonoBehaviour { private InfiniteScrollRect _infiniteScrollRect; private InfiniteScrollRect InfiniteScrollRect => _infiniteScrollRect != null ? _infiniteScrollRect : _infiniteScrollRect = GetComponent<InfiniteScrollRect>(); private void Awake() { InfiniteScrollRect.SetItemData(new object[] { 200f, 300f, 400f, 500f, 600f, 700f, 800f, 900f, 1000f }); } }

By scrolling, you can confirm that the width of the scroll item is updated for each set data (width).

To create a Nested Scroll View in the Unity Editor, go to GameObject → UI → Nested Scroll View. Put it under the Scroll View container.

When scrolling in the non-scroll direction of NestedScrollView, scroll event is sent to the parent ScrollView.
