Is there a way to add image galleries/slideshows that are nested under accordion style titles

Basically, I want to make my portfolio more categorized, and instead of all of the images being out there, I'd like to have them show up after the user taps or clicks on the title.

For example, initially they see just the categories such as "People" "Food" etc and then after clicking on them, the slideshow part opens up for that section. I hope that makes sense.

Attached a photo that hopefully illustrates what I have in mind better.

Thank you in advance for your help!

You mean Slideshow appears inside Accordion People/Food Item

or Slideshow will appear on right of accordion

?
