    To make your tag show in the email, you either need to add a name attribute to the form tag [optional] and include it as a variable and then update this line:

    
// Use this if you're using a tag attribute [option tag-name]
$html.= '<label>Scegli uno o più optional</label><select id="myFilter" class="multiple_select" name="'.$tag->name.'" multiple>';


// Use this if you just want it to work with [option]
$html.= '<label>Scegli uno o più optional</label><select id="myFilter" class="multiple_select" name="optional[]" multiple>';

    The email will read the "NAME" attribute of the input field or select
