EN

var yourData = [
{Name : "Forms", value : "Request"},
{Name : "Forms", value : "Report"},
{Name : "Forms", value : "Password"},
{Name : "Energy", value : "Report"},
{Name : "Energy", value : "CUstomer Multiplier"},
{Name : "Energy", value : "Product Feedback"},

  var html = '';

    html += "<div>"+data[i][0].Name+" </div>"+"<ul>";

// Do this before $.each()
var sql_data = {
    Forms: [],
    Energy: []
};


// Inside of $.each() do something like this:
sql_data[col_1].push(col_2);
