    @conschneider hello, and thanks for help me.
    I try insert onChange=”ponPaises(this.form)”
    on select.

    If my code es: 

    
<span class="select2-selection select2-selection--single" role="combobox" aria-haspopup="true" aria-expanded="false" tabindex="0" aria-labelledby="select2-region-container"><span class="select2-selection__rendered" id="select2-region-container" title="Europa"><span class="select2-selection__clear">×</span>Europa</span><span class="select2-selection__arrow" role="presentation"><b role="presentation"></b></span></span>

    and i need add onChange=”ponPaises(this.form)” on this span. Because i use a javascript.

    Hi again,

    Ah I see. You are trying to change the markup with that PHP function addAttributeToDropdown so it contains your event listener.

    * wp_dropdown_cats is deprecated.
    * Instead wp_dropdown_categories is encouraged.
    * But neither of those two are hooks. They are functions. Therefore: add_filter('wp_dropdown_cats','addAttributeToDropdown'); cannot work.

    You need a filter that is attached to the HTML output selection.
    Tell me which selection form you are trying to edit. Where can I see this?

    Kind regards,
