[Solved]-Highcharts - how to remove "Open in Highcharts Cloud" from the export menu-Highcharts

You can define the items in the exporting menu with exporting.buttons.contextButton.menuItems option.

If you want to exclude only openInCloud item then you can filter out it from the default menu items.

exporting: {
  buttons: {
    contextButton: {
      menuItems: Highcharts.getOptions().exporting.buttons.contextButton.menuItems.filter(item => item !== 'openInCloud')
    }
  }
}
