Specify that nav buttons («/») and/or the ellipsis (…) can be dropped for very narrow widths (useful if the component is used in narrow widths with high page numbers)

'dropEllipsis' - drop the ellipsis (…) for narrow widths
'dropNav' - drop the nav («/») for narrow widths
['dropNav', 'dropEllipsis'] - drop the nav initially and then further drop the ellipsis if required
['dropEllipsis', 'dropNav'] - drop the ellipsis initially and then further drop the nav if required

The default behaviour is to not drop these elements (this may change in a future major release)
