Microsoft is working on a Split Screen feature for Edge that will allow you to place webpages side-by-side within a single window. The feature reduces clutter by grouping pages within a single Edge interface. As a result, you only see one address bar, set of navigation keys, and other elements. Split Screen view also allows you to pair windows together.
Since Split Screen in Edge is still an experimental feature, you can expect to run into some bugs. The feature is also missing some core functionality, which is expected at this stage in development. For example, you cannot drag a tab into another split window. You can set it to open links in a split window, but that functionality has not worked smoothly in my testing.When you have pages split across two windows, they are paired together. That means that each Edge tab can hold up to two windows at once. It can be a bit tricky to navigate and there is a learning curve, since the layout is so different to the current version of Edge.
Here's how to enable Split Screen view within Microsoft Edge:Go to edge://flags through the address bar.
Search for "Split Screen" within flags.
Toggle the feature to Enabled.
