Expected behavior

Hi, I am using the "Gallery with image filtering" code too however there must be more js needed than the js you have in the snippet code because the filtering is not working.

Actual behavior Nothing happens. Same goes for the "Lightbox gallery with gutters". There are supporting files that have the zoom window icons that I cannot located. I downloaded the zip file with all the js for all the examples shown however it's too many files. There must be a way to just find the js files needed for those two components. Does anyone have any suggestions? Can you post exactly all the js needed to make the filtering from https://mdbootstrap.com/plugins/jquery/gallery/ work? Thank you :)
