Solved Why Item couldn't positioned in Row/Column in QML?

[Alien]

Hello,

Why Item in QML couldn't positioned in Row/Column?

  Column
    {
        Item {
            id: name0
            Rectangle
            {
                width: 50
                height: 50
                color:"blue"
            }
        }

        Item {
            id: name1
            Rectangle
            {
                width: 50
                height: 50
                color:"red"
            }
        }
    }

the red rectangle put on the blue?

@Alien
because the wrapper Items (around the rectangles) do not have a width/height set, so they are overlapping

@Alien give a width/height to your Item elements

Column
        {
           // anchors.fill: parent
            Item {
                id: name0
                width: 50
                height: 50
                Rectangle
                {
                     anchors.fill:parent
                    color:"blue"
                }
            }

            Item {
                id: name1
                width: 50
                height: 50
                Rectangle
                {
                    anchors.fill:parent
                    color:"red"
                }
            }
        }
