@amir.sanaat Hi, I think you could store the reference on the popup in you ListElement:

onClicked: popup.open()
...
ListElement {
    name: "Grey"
    colorCode: "grey"
    numbero:1
    popup: popid1
}

Another solution could be having only one popup and then using a loader to display the GUI according to numbero

Dear @Gojir4 thank you for snap reply
the way you said dosent work and i faced with "ListElement: cannot use script for property value" error.

@amir.sanaat Ok, was a long time I didn't code in QML, sorry. May be a switch can make the job. That's not very elegant but I think it will work. I don't have anything else yet.

onClicked:{
    switch(numbero){
        1: popid1.open()
        2: popid2.open()
    }
}
