Select widget is only for 1000 results(items)? In the manual is no limit for this.
1000 items is so few.
The limit of 1000 features likely comes from the Feature Service not the widget.
Yes I agree with Robert.
1000 is the number of returned records from the ArcGIS Server, it is not the limit from the widget itself.
Thank you rof answer. And it is possible change it in ArcGis Server? For 3000 records?
Sure see this thread:
