Marquee Selection (React)

Use the showMarquee property to add an Excel-style marquee to the grid.

You can customize the appearance of the marquee by styling the 'wj-marquee' class.

When the marquee is enabled, the grid does not highlight the active cell (like Excel). If you want to highlight the active cell, use a CSS selector based on the :focus pseudo-selector:

This example uses React.
