Knack doesn’t natively provide the ability to select multiple records from a table, so you’ll need to use JavaScript.
- Using JavaScript, add checkboxes to the table and a button.
- The user selects items from the table and clicks the button.
- When the button is clicked, the JavaScript submits each selected record to a form that adds a Shopping Cart item, using a View-Based API request.
Hope this helps.
