Understanding nested collections !

[VP200]

Hello,

I am having a hard time trying to understand how nested collections work in PowerApps. I have a very nested collection and want to extract information and display it in the gallery. I looked around on the internet but I only found basic examples of how to extract data. 

This is how my collection looks like:

ClearCollect(NestedListExample, {List01:{List01A: {List01AA: {List01AAA:{List01AAAA: "Book_ID01"}}, List01C: "Random"}, List01B: "ABC"}, List02: "Random info", List03: "Random info"}, {List01:{List01A: {List01AA: {List01AAA:{List01AAAA: "Book_ID02"}}, List01C: "Random"}, List01B: "ABC"}, List02: "Random info", List03: "Random info"},{List01:{List01A: {List01AA: {List01AAA:{List01AAAA: "Book_ID03"}}, List01C: "Random"}, List01B: "RRR"}, List02: "Random info", List03: "Random info"},{List01:{List01A: {List01AA: {List01AAA:{List01AAAA: "Book_ID04"}}, List01C: "Random"}, List01B: "ABC"}, List02: "Random info", List03: "Random info"})

level1level2level3level4

level5

If this makes any sense, I'm trying to display List01AAA items IF List01B== “ABC” inside a gallery.

Currently, I can only extract data from List01A (level2 image) data but nothing more than that :(. Any examples of how to extract data from nested collections would help. 

Thank you!
