    I want the TimelineDeviceDetail exactly at the position where I deleted it.

      So you have TimelineDeviceDetail.qml file. You can assign an id there.

        ... I don't get it, can you make a quick example? In my opinion the "delegate" just delegate the model to TimelineDeviceDetail and to make TimelineDeviceDetail visible I have to declare it somewhere in TimelineVertical...

          From your earlier posts i assume that you have a separate TimelineDeviceDetail.qml file. So define an id here.
          @
          import QtQuick 2.0

          Rectangle {
          // id: rectangle2
          id: detailRectangle
          width: 0
          height: 200
          color: "#FFFFFF"
          radius: 4
          anchors.right: parent.right
          ...
          @

          and it will be accessible as before.

              So just define an id (detailRectangle) there and it will be accessible. See my earlier edited post.

                So you mean:

                in TimelineDeviceDetail.qml

                @
                //detail
                Rectangle {
                id: detailRectangle
                width: 0
                height: 200
                color: "#FFFFFF"
                radius: 4
                anchors.right: parent.right
                anchors.rightMargin: 100
                opacity: 0.70
                anchors.left: timelineLineRectangle.right
                anchors.leftMargin: 165
                anchors.top: timeslotRow.bottom
                anchors.topMargin: 0
                visible: true //debugging: make it false

                    Text {
                        id: euroText
                

                // Component.onCompleted: console.log("euro: " + timeslotmodel.euro)
                text: model.euro
                anchors.top: parent.top
                anchors.topMargin: 20
                anchors.left: parent.left
                anchors.leftMargin: 20
                font.pixelSize: 12
                }

                    Text {
                        id: kwhText
                

                // Component.onCompleted: console.log("kwh: " + timeslotmodel.kwh)
                text: model.kwh
                anchors.top: parent.top
                anchors.topMargin: 20
                anchors.horizontalCenter: parent.horizontalCenter
                font.pixelSize: 12
                }

                    Text {
                        id: timeText
                        text: model.time
                        anchors.top: parent.top
                        anchors.topMargin: 20
                        anchors.right: parent.right
                        anchors.rightMargin: 20
                        font.pixelSize: 12
                    }
                

                //...
                @

                and int TimelineVertical.qml:

                @
                Repeater {
                id: deviceRepeater
                model: timeslotmodel
                delegate: TimelineDeviceDetail {}
                // Component.onCompleted: console.log("euroValueTest: " + timeslotmodel.euro)
                Button {id: deviceImageButton; anchors.verticalCenter: parent.verticalCenter; iconSource: deviceImage; width: 100; height: 100; /onClicked: setVisibleEffect(detailRectangle, deviceItem);/ style: TimelineDeviceButtonStyle{} }

                                        }
                                    }
                                }
                            }
                        }
                
                         TimelineDeviceDetail {} //set the view where I need it
                

                @

                But than I get the same error as before:

                qrc:///TimelineDeviceDetail.qml:22:19: Unable to assign [undefined] to QString
                qrc:///TimelineDeviceDetail.qml:33:19: Unable to assign [undefined] to QString

                  I put the code from TimelineDeviceDetail.qml back to TimelineVertical.qml to make it simple. It turned out that it's even there not accessible...

                  @
                  Row {
                  id: deviceRow
                  spacing: 20

                                          Repeater {
                                              id: deviceRepeater

                                              delegate: detailRectangle

                    If you define delegate in same file then you will need to encapsulate it in Component.

                    Going to the previous, you have again added TimelineDeviceDetail there. Please remove it or you will get the same errors. Please refer my earlier posts.
                    TimelineDeviceDetail will be accessible using its id even if it is specified in separate file.

                      Ok thanks for that advise. Can you please tell my if I remove "TimelineDeviceDetail" from "TimelineVertical" how to include the TimelineDeviceDetail in TimelineVertical? Or can you make "will be accessible using its id..." a little bit more clear?

                      Thanks

                        Ok. Just revisited the posts. I too got confused. Lots of code here :)
                        First Why would you want TimelineDeviceDetail outside the delegate as it has already been assigned as delegate to repeater ?

                        Just created a small example related to above:
                        @
                        //TimelineDeviceDetail.qml
                        import QtQuick 2.3
                        Rectangle {
                        id: detailRectangle
                        y: index*40
                        width: 300
                        height: 40
                        color: "lightgray"
                        Text {
                        anchors.centerIn: parent
                        text: model.euro
                        }
                        }

                        //main.qml
                        import QtQuick 2.3
                        Rectangle {
                        width: 300
                        height: 180

                        ListModel {
                            id: mymodel
                            ListElement {
                                euro: "3"
                            }
                            ListElement {
                                euro: "6"
                            }
                        }
                        
                        Repeater {
                            model: mymodel
                            delegate: TimelineDeviceDetail {}
                        }
                        

                        }
                        @

                        Here TimelineDeviceDetail is able to access the model role(euro).
                        Now can you format your question and requirements according to above example so it will be easier for me to understand?

                          That's a good idea to simplify that. Did you compile the example?

                          I get the following error:

                          @
                          qrc:///TestTimeline.qml:12: ReferenceError: model is not defined

                          }
                          

                          }

                          TestTimeline.qml:

                          }
                          }
                          @

                          I made some little changes on your code.

                            I set up a new project just to test this little example and the same here. Any suggestions?

                              I fixed this with JavaScript, probably not this best way but it works for me...

                              TimleineVertical.qml:

                              @
                              Row {
                              id: deviceRow
                              spacing: 20

                                                      Repeater {
                                                          id: deviceRepeater
                                                          model: attributes
                              
                                                          Button {id: deviceImageButton;
                                                              anchors.verticalCenter: parent.verticalCenter;
                                                              iconSource: deviceImage;
                                                              width: 100;
                                                              height: 100;
                                                              onClicked: setVisibleDetail(detailRectangle, deviceItem), setTest(euro, kwh, time, euroText, kwhText, timeText)
                              
                                                              style: TimelineDeviceButtonStyle{} }
                              
                                                      }
                              

                              @

                              JavaScript to set the values from the model for the text element:

                              @
                              function setTest(euro, kwh, time, euroText, kwhText, timeText) {
                              euroText.text = euro;
                              kwhText.text = kwh;
                              timeText.text = time;
                              }
                              @

                              Text element:

                              @
                              Text {
                              id: euroText
                              anchors.top: parent.top
                              anchors.topMargin: 30
                              anchors.left: parent.left
                              anchors.leftMargin: 20
                              font.pixelSize: 12
                              }
                              @
