Sidecar map zoom using mouse scroll

[RobbieCook]

In Sidecar, you can only zoom in and out by using the + and - buttons. There should be the option to 'Enable map scroll'. Many users are used to using a mouse scroll to zoom in and out.

Alternatively, the Sidecar will know whether you're hovering over the map or the text at the side. If you are over the map and use the mouse scroll, it zooms in/out on the map. If you are over the text at the side, it scrolls up/down the page.

I believe the solution is already implemented when you have webapps or experience builder apps in the sidecar (instead of a webmap).  You get a pop up that enables the scroll wheel to zoom/pan after clicking on the map:

After clicking on the map, hovering over the text will go back to scrolling through the text and sidecar tabs. 

In addition to the + and - buttons, there is also a button on the top right to expand the page on both webmaps and webapps. After clicking on it, you can use the scroll wheel to zoom.

@RobbieCook -- I don't think that we would look to implement this as our research indicates it would be a very poor experience for most readers. If scrolling zoom was enabled on a sidecar map there is a strong likelihood readers would inadvertently zoom the map simply by scrolling into the sidecar. Controlling the zoom based on the cursor location is not something most readers would be aware of, so it would not solve the problem.

In many cases, we recommend that you look to create a story that eliminates the need for your readers to manually navigate the map at all. This can make reading a story much more enjoyable for the audience since they don't have to worry about where to pan or zoom the map. You can accomplish this using a technique called map choreography, which you can learn more about here: Choreograph your maps with ArcGIS StoryMaps (esri.com). You can also use a feature called map actions to create buttons or links that move the map to specific areas or turn layers on/off. This is another way to make your story easier to use for the audience. You can read more about map actions here: Supercharge your stories with map actions (esri.com).
