I have been working on Web AppBuilder for a while now. There are two ways to create the application using Web AppBuilder.
1. Web AppBuilder Online - For this we do not need anything to download
2. Web AppBuilder for Developers - Which requires to download the Developer package and create the application modify it locally and host it through your web server.
We have an enterprise arcgis online account and I have developed some custom themes and custom widgets using WAB for Developers version.
My question is that is there a way that I can incorporate these custom themes and widgets in the online version on Web AppBuilder.
By have this capability, the other members of our team can create applications using the online version of WAB using the custom themes and custom widgets also.
Please feel free to ask more clarification if my question is not clear.
