Angular ngx daterangepicker z-index

You need to use the overflow attribute as there is no space for the calendar. I think it will resolve your issue.

.md-drppicker {
  z-index: 9999;
  overflow: auto; // also try overflow-y;
}

ngx-daterangepicker-material {
  z-index: 9999;
  overflow: auto; // also try overflow-y;
}

I would suggest you to attach a stackblitz instance if issue still persist.
