The Top Navigation Theme completely moves the native Sidebar Menu to show across top of the screen.
Example:
Use a Preset to start building building your Top Navigation Theme.
To set up the Top Navigation Theme, click on the "Presets" tab.
Next, scroll down to view Presets and click the "Set" button to choose a Preset.
Enable the toggle switch from "Deactivate" to "Activate".
Click the orange "Publish" button to make your changes live.
If you are not ready to publish yet, you can use "Preview Mode" (click the orange "Open draft realtime preview" link in the top-right) to see your changes instead.
