+If the `CommonProperties` component is nested inside single or multiple layers of `<div>` elements, special consideration is needed for proper layout behavior.
+
+```html
+    const rightFlyoutContent = (
+      <div className="parent-div">
+        <CommonProperties
+          propertiesInfo={this.propertiesInfo}
+          propertiesConfig={{ containerType: "Custom", rightFlyout: true }}
+          callbacks={this.callbacks}
+        />
+    </div>
+)
+
+`display: flex` should be added to `parent-div` to allow Common Properties content to occupy full width and height available in right flyout.
