It works with handlebars builtin helper lookup
added default {{#each}} loop from handlebars.
<select name="" id="">
<option value="">Select</option>
{{#each this.select_values}}
<option value="{{lookup this ../this.opt_value}}"> {{lookup this ../this.opt_label }} </option>
{{/each}}
</select>
Special thanks for #Tamlyn for explanation on lookup helper.
