Hey @qlmoffat, happy to help here!
I'd first like to share our checkbox tree documentation which is really helpful for showing how the data is formatted for the different component properties.
Based on what you've sent, I plugged it into a test checkboxTree and got it to show up by adding commas at the end of the lines and putting quotes around "children". Here's what I typed followed by a screenshot:
[
{
"label": "Economy, Finance and Trade",
"value": "CL",
"children": [
{
"label":"GVA from Manufacturing",
"value" : 84
}
]
}
]
Is there anything specific I can help you with with your checkbox Tree?
