Trigger the slider outside the slider

Sorry if it’s been asked, I did look. I’d like to build a custom nav for the slider, so that buttons around the slider, trigger slide X when clicked. E.g. buttons - ‘shoes’ - ‘socks’ - ‘slippers’ when clicked show all the wonderful information on shoes or socks or slippers in the slider.
Is there a simple way to add the trigger to a button so it makes the slide go to SLIDE X ?
Thanks
