Hi

For X-cart 4.3.0 version
Your: modules/Manufacturers/menu_manufacturers.tpl should look like this.

{if $manufacturers_menu ne ''}
{capture name=menu}
<form name="form_manuf" method="get" action="manufacturers.php">
<select name="manufacturerid" onChange="document.form_manuf.submit()">
<option value="0" selected>Seleccionar Artista</option>
{section name=mid loop=$manufacturers_menu}
<option value="{$manufacturers_menu[mid].manufacturerid}">{$manufacturers_menu[mid].manufacturer|truncate:15:"...":true}</option>
{/section}
</select>
</form>
{/if}
{/capture}
{include file="customer/menu_dialog.tpl" title=$lng.lbl_manufacturers content=$smarty.capture.menu additional_class="menu-manufacturers"}
