select2 placeholder showing empty option

Question

too add a placeholder in select2 i have to add an empty option tag in the code like this

<select id="e2" name="rol_id" >
                       <option><option>
                       {foreach from=$data.roles item=rol}
                       <option value={$rol.rol_id}>{$rol.rol_nombre}</option>
                       {/foreach}
 </select>

but when i do that i get this option empty that is selectable

how can i not show that option but still the placeholder?

Thanks!

You have a syntax error on 2nd line.

<option></option>
