Problem ps_languageselector - language_code instead of iso_code

[jotas torres]

Hi, 

I have a problem with the module ps_languageselector.  I need to change the   hreflang="en" to hreflang="en-US". I know I have to use the variable language_code  instead of  iso_code but I don't know where I have to change it. Could you help me please? 

 

Final Code

<div id="language_selector" class="d-inline-block">
    <div class="language-selector-wrapper d-inline-block">
        <div class="language-selector dropdown js-dropdown">
            <a class="expand-more" data-toggle="dropdown" data-iso-code="es"><img src="https://url/img/l/3.jpg" alt="Español" class="img-fluid lang-flag" /> Español <i class="fa fa-angle-down" aria-hidden="true"></i></a>
            <div class="dropdown-menu">
                <ul>
                                            <li >
                            <a href="https://url/en/" rel="alternate" hreflang="en"
                               class="dropdown-item"><img src="https://url/img/l/1.jpg" alt="English" class="img-fluid lang-flag"  data-iso-code="en"/> English</a>
                        </li>
                                            <li  class="current" >
                            <a href="https://url/es/" rel="alternate" hreflang="es"
                               class="dropdown-item"><img src="https://url/img/l/3.jpg" alt="Español" class="img-fluid lang-flag"  data-iso-code="es"/> Español</a>
                        </li>
                                    </ul>
            </div>
        </div>
    </div>
</div>
