Problem width multiple ApplicationWindows activefocusitem and requestActivate()

[jimmy60805]

Hello,

I wanted to build a customized a two-layer menu by ApplicatioWindows.
Like following picture. The first applicationwindow would side from right of background window and the second one would side out when clicking the first layer.

Also I want to design the effect of hiding both applicationwindows when clicking outside applicationwindows.
Can anyone help me with this problem?

PS. following code is the desired property of applicationwindow

ApplicationWindow {
    flags: Qt.WindowStaysOnTopHint | Qt.Popup | Qt.FramelessWindowHint | Popup.CloseOnPressOutside
}

Thank you
Best Regared,
Jimmy
