    Spreadsheet has support for responsive behavior based on client browser’s width and height. To enable responsive, set is-responsive property in e-scroll-settings as true. The three modes of responsive layout available in Spreadsheet based on client width are,

    • Mobile(<420px)
    • Tablet (420px to 617px)
    • Desktop(>617px)

    NOTE

    Default value of is-responsive property is true.

    Mobile Mode

    If client width is less than 420px, the spreadsheet will render in mobile mode. In which, you can see that spreadsheet user interface is customized and redesigned for best view in small screens. The customized feature includes filter dialog, format dialog, chart type dialog and ribbon.
