CPT Categories widget queries

Hi,

I’ve got a few queries about the CPT Categories widget.

1) Can you advise how I can get the widget aligned to the centre of my site. At the moment it seems left-aligned. I’ve poked around using “inspect element” to see if I can figure out what needs changing with CSS but with no joy.

2) IS it possible to use CSS to hide a particular category on the CPT Categories widget? I have a special category which is used but I’d prefer not to show on the CPT Categories widget.

3) I don’t want to initially show the sub-categories, however, would it be possible to add a way of drilling down to show the sub-categories

Hope these make sense.

Cheers,
Mark
