Non-escaped select2 placeholder on multiple select

问题

I think I understand how placeholders work regarding select2 library.

There is a thing bugging me for a while already, how to have non-escaped placeholder on multiple selects.

The reason is I like to place an icon at the placeholder.

Single selects uses an additional option tag and the property escapeMarkup at the select2 options object.

$('mySelector').select2({
    escapeMarkup: function(markup){
        return markup;
    }
});

Nothing of that is possible at multiple selects since the placeholder is placed at an input tag, so html markup is escaped and you get the <i> tag instead of the icon.

Is there a workarund for this?

@Marcos i have done some solution regarding placeholder regarding select2 library.

<select class="select2 selectPlaceholder" multiple="multiple"></select>

<script>
  $(".selectPlaceholder").select2({
    placeholder: "Select Product",
    allowClear: true
  });
</script>

Optional

allowClear: true

Please let me know if i am right because i got your question but still i have some doubt understanding Que.

Taking your previous comment as a reference:

"the idea is to place a font awesome icon at the placeholder and preventing select2 from escaping it, and i'm getting the i tag instead of the icon"

...and if I understood correctly, you want to place a Font Awesome icon on the Placeholder of the Select2 element and keep it there, correct?

Check the following code where I'm inserting a DIV that contains a Font Awesome icon (the little airplane) and placing it on top of the Input used for searching. Even when you select different items from the Select (is a Multiple Select as you needed) the icon remains in the placeholder and also it has a text by default.

Remember to add the class="tab" in case you don't see the Icon.

$(document).ready(function(){
  $("#sel1").select2({
    placeholder: 'Search here...',
    allowClear: true
  });
$(".select2-search.select2-search--inline").prepend("<div class='fab'>&#xf374;</div>");
});

select {
    width:300px;
    }
.multi {
    padding:10px;
	font-family: FontAwesome, "Open Sans", Verdana, sans-serif;
    font-style: normal;
    font-weight: 600;
    text-decoration: inherit;
}    
.top {
    position: absolute;
    left: 0px; top:0px;    
    }
