When building dynamic interfaces that show or hide content—such as tabbed menus or conditional profile sections—the method you choose to hide elements significantly impacts application stability and performance.

The Hidden Cost of Display None

Using the Display: None property in the Appearance Panel technically hides a component from the user's view. However, under the hood, Shipcode may still attempt to render that component and calculate its dimensions.

If a component is complex or relies on specific data, this "hidden" rendering can lead to:

• Incorrect Dimension Calculations: The app may struggle to calculate the size of an element that isn't visible.
• Console Errors: A stack of rendering errors can accumulate, potentially leading to application crashes.
• Bloated HTML: Even if the user can't see it, the component still exists in the underlying code.

A Better Practice: Data Zone Slots

For a more stable and efficient experience, use Data Zones and the Active Slot logic to manage visibility.

Instead of just turning the visual display off, the slot system controls whether the component is actually rendered in the application.

• Active Slot Logic: By wrapping your content in a Data Zone and utilizing slots, Shipcode only renders the specific "active" part of your UI.
• Clean Rendering: Components in inactive slots are not rendered in the HTML at all. This prevents the system from attempting to calculate dimensions for hidden items and keeps your application running smoothly.

Whenever you need to toggle between different views or sections, prioritize the use of Data Zone Slots over the Display property for better performance and reliability.
