This is for MRTK in Unity for us on Hololens 2.

I imported the Scrolling Object prefab. The buttons are populated dynamically at run time.
I can scroll the list in the Unity Editor (with difficulty), however, when I release the mouse the list reverts backwards. How can I remedy this problem.

    Hello, Welcome to Microsoft Q&A,

    Thanks for the reply. Firstly, for the clarification, the component – Scrolling Object Collection provides a feature for the scroll objects to prevent the scrolling content from being dragged out of the clipping bound. When the scroll container is scrolled to the end, and it can't fill the scrolling viewable area, the scrolling container would bounce back to fill the scrolling viewable area after you release the mouse. It’s by design. If you want to disable this feature, you can navigate to the component [Scrolling Object Collection], uncheck the option [Disable Clipped Game Objects].
    If the issue you mentioned happened in every dragging. You may need to check the settings of the [ScrollingObjectColllection]->[Page Cell]. As this section – [Configuring the scrolling viewable area] (https://learn.microsoft.com/en-us/windows/mixed-reality/mrtk-unity/features/ux-building-blocks/scrolling-object-collection?view=mrtkunity-2021-05#configuring-the-scrolling-viewable-area) said, the width, height, depth should be changed to the dimensions of the content items, for this situation, it should be the dimension of the button. Otherwise, it may cause the offset of the scrolling.
