Once you’ve added your specification, and you are presented with the Design mode of Designer follow these instructions to enable / disable Live Preview:
- Open your OpenAPI document
- Click the Editor icon (if you are not already in the Editor view)
- Click the “Preview: On” or "Preview: Off" button to show / hide the Live Preview pane.
Once enabled a live preview of your document will display to the right of the text editor pane, and as you make changes to the document the preview pane to the right of the text editor will instantly update to reflect the changes made.
