Building a Tree of Pages - Is there a Way to Show the List of Children Nodes and Edit View?

Hi there, I'm building a tree of pages, is there a way in the structure builder, a node of my tree can be just a level of the hierarchy and have also an edit view? so on click I show the list of children nodes but also the edit view for that node?

((I am still learning structure, so forgive the rough code that I’m sure can be optimized quite a bit)) - I broke out the mainCompany variable so the other devs working on this project could more easily enter a different document by title without having to know strucutre builder methods, with a rough plan to break this and similar values out into an imported constants list for them.

cool thanks for that, it feels like what I am after is doable, I just need to play with structure builder and go beyond what's in the documentation.
