# Welcome to the Highcharts Gantt JS (gantt) Options Reference

These pages outline the chart configuration options, and the methods and properties of Highcharts objects.

Feel free to search this API through the search bar or the navigation tree in the sidebar.

# accessibility.enabled

Enable accessibility functionality for the chart. For more information on how to include these features, and why this is recommended, see Highcharts Accessibility.

Highcharts will by default emit a warning to the console if the accessibility module is not loaded. Setting this option to `false` will override and silence the warning.

Once the module is loaded, setting this option to `false` will disable the module for this chart.
