- Always preview before saving to make sure everything looks correct.
- Keep a backup of your CSS files if you maintain multiple themes.
Hide cancel button
Hide the Cancel button at the bottom-right corner of the importer. The X (close) button at the top-right corner stays. Hiding Cancel helps prevent users from abandoning the import by accident and keeps them focused on the Submit button, which suits workflows where you want to guide users toward submission. Default:No
