    In some case I need to set the pickingmode of parent to Ignore, but its children need to be clickable

    Actually this should be the behaviour of pickingMode = Ignore. It only affects the element, not its children.

    Thanks, but I don't know why it doesn't work for me, I had tried it before.
    Here's what I'm doing:
    Code (CSharp):
    1. root.Add(errors = new VisualElement());
    2. errors.pickingMode = PickingMode.Ignore;
    3. errors.style.position = Position.Absolute;
    4. var label = new Label("some error");
    5. label.style.color = Color.red;
    6. label.RegisterCallback<ClickEvent>(evt =>
    7. {
    8.    //Locate error
    9. });
    10. errors.Add(label);

    I think you want to make sure you set the useTrickleDown parameter to TrickleDown in your RegisterCallback call, as by default it's BubbleUp.
