I have 10 layers with different aerial imagery. I need to use them in time slider widget. How can I do it? Thanks
For configuring Web App Builder time slider see here
Time Slider widget—Web AppBuilder for ArcGIS (Developer Edition) | ArcGIS for Developers
First you have to prepare your mosaic dataset to be time aware
Time in a mosaic dataset—Help | ArcGIS for Desktop
then publish this mosaic dataset as image service
This image service is compatible with time slider Web GIS providing.
