If so can anyone point me to resources on the topic?
Web AppBuilder does NOT support disconnected/offline editing workflows.
Hope this helps,

No. Another requirement for disconnected editing workflows is for the client app to be able to store a local copy of the data that you would be editing offline, as well as sync that data back to the original source data (via a feature service). Web AppBuilder does NOT support this type of capability.
I was trying to figure out the same thing, and came across ESRI's Offline-editor-js project on GitHub. It looks like this may be a possible solution, provided you have some knowledgeable developers on your team.
