SpreadsheetWeb offers several ways to customize the user interface of a SpreadsheetWeb application:
1. You can customize the layout of your application using our drag-and-drop application builder, Designer.
2. You can customize the look and formatting of your application using our Stylesheet module.
3. We also support embedding custom code called Custom Action to handle more advanced user interface features. Unfortunately, the Custom Action feature is only available in private cloud and server licenses.
While there are ways to customize the user interface of your SpreadsheetWeb application, it may not be possible to match your user interface requirements 100%.
