I am using Jquery-option-tree plugin on a standalone website not based on Wordpress as in example 7 on the demo page, except that I am not passing a .txt file but a PHP page is generating the array of < options > to be passed to the plugin.

This perfectly works: so let's say that the user wants to select a category for a new product, the plugin suits the purpose generating a nice: " Food -> fruit -> apples " upon user clicks. (see demo page ex. 7)
What instead if a product already exists with its categories assigned? I want to show it to the user when he edit that product, preloading the tree.
I have the ids path coming from database, so it would just be a matter of having the plugin to run without the user interact, using the value I pass. I saw this question: jQuery simulate click event on select option and tried to simulate user' click with this (and other) methods with no luck.
$('#select')
.val(value)
.trigger('click');
Here the call to the function:
$(function() {
var options = {
empty_value: '',
set_value_on: 'each',
indexed: true, // the data in tree is indexed by values (ids), not by labels
on_each_change: '/js/jquery-option-tree/get-subtree.php', // this file will be called with 'id' parameter, JSON data must be returned
choose: function(level) {
return 'Choose level ' + level;
},
loading_image: '/js/jquery-option-tree/ajax-load.gif',
show_multiple: 10, // if true - will set the size to show all options
choose: ''
};
$.getJSON('/js/jquery-option-tree/get-subtree.php', function(tree) { // initialize the tree by loading the file first
$('input[name=parent_category_id]').optionTree(tree, options);
});
});
Here you can see the plugin:
