 </div>
 <div class="col-md-7 col-sm-8 ">
    <select id="membre_interne" name="x_membre_interne"  widget='many2many_tags' class="form-control " >
       <option value="" >Sélectionnez...</option>
       <t t-foreach="users" t-as="user" >

       <option t-att-name="x_membre_interne"  t-att-value="user.login"   >
         <t t-esc="user.login" widget="many2many_tags"/>
       </option>
