mustache partial not looping through the data passed down to it

Question

I am using mustache in conjunction with enter link description herepattern lab to render out a list of items from a json data file. Given this data structure:

{
  "states": {
    "dropdown": {
      "items": [
        {
          "title": "CA"
        },
        {
          "title": "OR"
        },
        {
          "title": "TX"
        }
      ]
    }
  },
  "roles": {
    "dropdown": {
      "items": [
        {
          "title": "Mid-level Office Manager"
        },
        {
          "title": "Facility Manager"
        },
        {
          "title": "Resources Coordinator"
        }
      ]
    }
  }
}

If I do the following within my partial:

{{#states}}
  {{#dropdown.items}}{{title}}{{/dropdown.items}}
{{/states}}

The names render out fine.

But if I do this:

{{#states}}
  {{> molecules-dropdown-picker(btnDropdownToggleLabel: "OR")}}
{{/states}}

Where the dropdown picker partial has the following code:

{{#dropdown.items}}{{title}}{{/dropdown.items}}

It won't render. What am I doing wrong?

Answer 1

I figured this out by doing the following:

JSON:

{
  "states": {
    "inputTextLabel": "State",
    "inputTextName": "address_state",
    "btnDropdownToggleLabel": "OR",
    "dropdownPickerItems": [
      {
        "dropdownItemTitle": "OR"
      },
      {
        "dropdownItemTitle": "TX"
      },
      {
        "dropdownItemTitle": "UT"
      }
    ]
  },
  "roles": {
    "inputTextLabel": "Company Role",
    "inputTextName": "company_role",
    "btnDropdownToggleLabel": "Facility Manager",
    "dropdownPickerItems": [
      {
        "dropdownItemTitle": "Facility Manager"
      },
      {
        "dropdownItemTitle": "Resources Manager"
      },
      {
        "dropdownItemTitle": "Mid-level Manager"
      }
    ]
  }
}

FORM:

{{#states}}
  {{> molecules-dropdown-picker-list}}
{{/states}}

DROPDOWN-PICKER-LIST:

<div class="dropdown-picker js-dropdown">
  <ul class="dropdown-picker__list js-dropdown-list">
    {{#dropdownPickerItems}}
      {{> atoms-dropdown-picker-item}}
    {{/dropdownPickerItems}}
  </ul>
</div>

DROPDOWN-PICKER-ITEM:

<li class="dropdown-picker__item js-dropdown-item">
  {{dropdownItemTitle}}
  <span class="dropdown-picker__selected-check">
    {{> atoms-icon(icon-type: "check-small") }}
  </span>
</li>
