- Focus management in interactive data grids is challenging, especially for keyboard users.
- Tab roving improves navigation by allowing arrow keys to move focus within the grid, treating it as a single interactive element.
- The `tabindex` attribute is crucial for controlling focus order and making elements tabbable or non-tabbable.
- Implementing tab roving involves tracking the focused element, handling key presses, and programmatically updating focus.
- React can be used to manage state and refs for dynamically updating the focused cell in a grid.
- Additional accessibility improvements include shortcuts for navigation and considering edge wrapping behavior.
- Tab roving is applicable beyond grids, such as in mega menus or custom numerical inputs.
