How to use an angularJs filter on items label within ng-options

Question

Given a select list loaded with product options, I want the label to be in the format of option name and then price in parenthesis. So for example: "Product Option B ($1,432.12)". My option object has the properties "name" and "price". Price is numeric, I want it formatted with the currency filter. How would I do this? I'm thinking maybe a custom filter that takes a string and numeric value. Just not sure how I would be able to apply the filter within ng-options.

The following code just displays the name (not price):

<select class="form-control"
        ng-model="selectedOption"
        ng-options="option.name for option in category.options"></select> 

Answer 1

This should work for you:

<select class="form-control"
    ng-model="selectedOption"
    ng-options="option.name + ' (' + (option.price | currency:'USD$') + ')' for option in options">
</select>

This will render a drop-down with items in this form: Item A (USD$14.00)
