I have reviewed many very nicely developed applications utilizing AGOL/Portal webmaps similar to the following: Where Are the Centers for Education Innovation? - A story map presented by Esri .
Besides the basic bootstrap/dojo tutorial, are there any current js api templates that incorporate the responsive nature (collapsing side menu) but use the ArcGIS Server REST endpoints (not webmaps from AGOL/Portal)?
I know this will require more js coding because I will have to individually build all the features that come "packaged" with a webmap. I am hoping to use some js dijits the complete the application. I would just like to start with a contemporary responsive js template and I really like the look of the storytelling templates for webmaps.
