About This Article
React Native developers struggled with layout complexity when building wrapper components. These components needed to handle events without changing how child elements positioned themselves. The typical solution required multiple nested Views, which made the visual hierarchy harder to manage and created confusing interaction boundaries.
React Native's New Architecture added support for the display: contents CSS property. This lets elements be removed from the layout structure while keeping their children's layout boxes intact. Events still propagate correctly through the flattened view hierarchy.
Developers can now build simpler wrapper components by skipping unnecessary layout boxes. This cuts down file complexity. What used to take three Objective-C files now fits in a single AppDelegate.swift. Event handling works the same way on both iOS and Android.
