ng selectize use array as source

[shafaqkazmi]

How to map string array to ng selectize data. One solution is to add extra mapping like:

var items = data.map(function(x) { return { item: x }; });
$('#input-tags').selectize({
         options: items,
        labelField: "item",
        valueField: "item",
        searchField: ['item']
    });

But I don't want to introduce extra mapping on UI. Is there any better solution to tackle this scenario?
