Hi, @jowitty, you can use a model like this:
{
categories: [<Node>]
}
Node:
{
"fieldToFilterBy": <String>
"child": <Node>
}
You’ll set child’s value to null if it’s a leaf.
Then you’ll be able to solve your task by performing $graphLookup.
Edit: On second thought I realize that your data structure is more an array of arrays than a tree. So maybe the simple solution is like you suggested:
{
"categories": [],
"fieldsToFilterBy": [
{
"listPath": [{fieldsToFilterBy :"1"}, {fieldsToFilterBy :"2"}, {fieldsToFilterBy :"3"}]
},
{
"listPath": [{fieldsToFilterBy :"5"}]
}
]
}
Both options have cons and pros.
Good luck,
Rafael,
