              <div include="form-input-select()">
  <select required>
      This is how we can do "placeholder" options.
      note: "required" attribute is on the select
    <option value=""
    >Example Placeholder</option>

    <!-- normal options -->
    <option value="1">Option 1</option>
    <option value="2">Option 2</option>
    <option value="3">Option 3</option>
    <option value="4">Option 4</option>
    <option value="5">Option 5</option>
