portfolio sub catogories only visible when clicked

https://prnt.sc/r0pg19

I hope I explain it well. above you see a filter with my main catogories in green and the sub catogories in red. I would like the sub catogories to be visible only when their main catogory is clicked. So if you click on landschapen, for example, then you will see the subcategories 2011 and 2012. How can i realize this? Kind regards
