I have a folder structure I'd like put into an html select using angular.
I've created an example below showing the structure and outputting it into a nested list structure. I've also put it into the select, but that only shows the top level of folders. Is there a way to have select show all the folders with indentation so you can visually see the structure in a select?
I can possibly add another property to the folders with the depth of the folder to help with the indentation. The folders are user defined in the system so I do not know how many levels it'll have without looking at the data.
Thanks

Reset to default 6Convert your folder structure into a flat list of objects, each of which would have a level property. You can then use this property to visually indent the values in the select element.
var app = angular.module("selectFolderApp", []);
app.controller("selectFolderController", ['$http', '$scope',
function($http, $scope) {
var ctrl = this;
ctrl.folders = [{
"name": "Housing",
"id": "1",
"children": [{
"name": "Datasheets",
"id": "2",
"children": [{
"name": "Folder 1",
"id": "3",
"children": []
}, {
"name": "Folder 2",
"id": "4",
"children": []
}]
}, {
"name": "Charts",
"id": "5",
"children": [{
"name": "Folder A",
"id": "6",
"children": []
}, {
"name": "Folder B",
"id": "7",
"children": []
}, {
"name": "Folder C",
"id": "8",
"children": [{
"name": "Sub Folder 1",
"id": "9",
"children": []
}, {
"name": "Sub Folder 2",
"id": "10",
"children": []
}
]
}, {
"name": "Folder D",
"id": "11",
"children": []
}, {
"name": "Folder E",
"id": "12",
"children": []
}]
}]
}, {
"name": "Road Works",
"id": "13",

"children": [{
"name": "Folder 1",

ctrl.flatFolders = [];
ctrl.folders.forEach(function (item) {
