How can I add a Buffer widget to my web app (built using web app builder)? (Note: Geoprocessing widget does not support ArcGIS Online Spatial Analysis Services)

TaN

I am creating a web app of all DC Public Schools and nearby green spaces (waterbodies, libraries, parks, etc) Please see: ArcGIS Web Application. Ideally, I would like to let teachers type in their school name and check off a buffer radius. The teacher would hit a "Search" button and  the web app would display the map- zoomed in on the school, with the desired buffer. Any thoughts on how to add a Buffer widget? *Would I need to build the widget using the Javascript API? Thank you so much for your help!

Ta N,

   Based on your requirements you probably need to develop your own widget for WAB.

1. You would begin by getting the WAB Developer version.
2. When you have the WABD (Web AppBuilder Developer) installed you will find a folder under widgets called samplewidgets. In that folder are sample to help you begin and a template.
3. You can find more help getting started by referring to the online help: Create a custom in-panel widget—Web AppBuilder for ArcGIS (Developer Edition) | ArcGIS for Developers

There are some custom widgets out there that do buffering like my eSearch Enhanced Search Widget Version 1.1.9 - 7/2/15 but it is probably more complex then what you are needing.
