Phones:

📞

👉 This is a simple form to show the power of SmarkForm.

👉 Tinker with it, modifying data, adding or removing items from the Phones list, sorting its items by dragging them and then clicking the Export button to see resulting data.

👉 Note that it enforces default behaviors, such as requiring a minimum of one item and excluding empty list items during export. But it can be easily changed, with properties like min_items and exportEmpties.

👉 Check the JS tab to see the little JS just to initialize it as a SmarkForm and show you the data when exported.
