webix window ui always on top of screen

hi i have window ui view with modal true parameter, and some times (by set interval) small dialog is overlay it, is there some property for window ui to stay always on top of screen (z-index: 999 maybe or something else), and when close it to see the dialog ?

Hi, @roma ! Could you please share a small example of described issue?
If you use webix.message as a dialog the reason can be that its z-index: 1000 by default and changing it may solve the problem.

  .webix_message_area {
  z-index: 1 !important;
}
