I have to convert a JSON file to a tree in a special div.
Convert the JSON to a Javascript object isn't a problem but I encounter some issues with the recursive function to display the tree into my div.
What works : my recursive function allow me to display all the child in the console.
What doesn't : I can just display the first children into the div and not the children of the first children. I think that the issue come from the method "appendChild".
I would be grateful if you can help me.
JSON code :

My JS code :
var treeModule;
treeModule = document.getElementById("json").innerHTML;
treeModule = JSON.parse(treeModule);
console.log(treeModule);
function Recursive(objetJS, isFirstParent) {
var list = document.createElement("ul");
for(let child of objetJS.children) {
var item = document.createElement("li");
item.innerHTML = child.name;
item.setAttribute('type', child.type);
console.log(child.name);
if(typeof(child.children) == "object") {
Recursive(child, false);
}
list.appendChild(item);
}
if(list.parentElement != null) {
item.appendChild(list);
}
if(isFirstParent == true) {
var htmlElement = document.getElementById("html");
htmlElement.innerHTML = '';
htmlElement.appendChild(list);
}
}
Recursive(treeModule, true);
