Choose options with selectize.js including option separators

My list of countries includes options with dashes as separators, but when I use selectize they disappear. How can I visually separate items in the list without using labelled option groups?

<select class="form-control" id="Country" name="Country">
    <option disabled="disabled">-------------------</option>
    <option value="AU">Australia</option>
    <option value="NZ">New Zealand</option>
    <option value="GB">United Kingdom</option>
    <option value="IN">India</option>
    <option value="US">United States Of America</option>
    <option value="ZA">South Africa</option>
    <option value="CA">Canada</option>
    <option value="IE">Ireland</option>
    <option value="SG">Singapore</option>
    <option disabled="disabled">-------------------</option>
    <option value="AF">Afghanistan</option>
    <option value="AL">Albania</option>
    <option value="DZ">Algeria</option>
    ...

Is there a way to achieve this separation in selectizejs without losing the separator options?

Answer №1

The reason for their invisibility is due to the absence of any value assigned to them. Consider assigning a null value in order to make them visible.

<select class="form-control" id="Country" name="Country">
    <option value="XX" disabled="disabled">-------------------</option>
    <option value="AU">Australia</option>
    <option value="NZ">New Zealand</option>
    <option value="GB">United Kingdom</option>
    <option value="IN">India</option>
    <option value="US">United States Of America</option>
    <option value="ZA">South Africa</option>
    <option value="CA">Canada</option>
    <option value="IE">Ireland</option>
    <option value="SG">Singapore</option>
    <option value="XX" disabled="disabled">-------------------</option>
    <option value="AF">Afghanistan</option>
    <option value="AL">Albania</option>
