 ## Early access feature
 
 If you have enabled early access then you will have a different navigation experience. This topic calls out both experiences.
 
 Your administrator has to opt in to early access updates for your environment and then install the updates to get this feature. More information: [Opt in to early access updates](https://docs.microsoft.com/power-platform/admin/opt-in-early-access-updates)

+## Reflow 
+
+The Unified Interface is designed for a modern reflow experience. 
+
+For forms, there are pixel breakpoints that cause information on a form to move on the screen based on the space available for the form to display in. This happens when the display space available to the form decreases. For example, if you resize the window that your app is in and decrease the width of the window it will decrease the space available for the form to display in. When the width decreases past certain breakpoints, information that would be hidden will move below where it used to be so that it is either visible or you can vertically scroll down to see it.
+
+When columns in a form section reflows from multiple columns to one column, it reflows from left to right (in left-to-right languages). When a control spans at least two columns in a section, then it reflows from top to bottom. The difference in behavior is so that tab navigation order is kept after reflow.
+
+In example below, each number corresponds to a control.
+
+|Reflow experience from left to right: When multiple columns reflow to one column   |Reflow experience from top to bottom: When a control spans at least two columns in a section (notice control #5 spans across) |

 ## Navigation
 
 The menu options let you swiftly navigate the different apps in the system. They provide quick access to recently viewed records and pinned favorites.
