 <?php
 
-namespace DropshippingXmlVendor\WPDesk\Forms\Field;
+namespace WPDesk\Forms\Field;
 
-use DropshippingXmlVendor\WPDesk\Forms\Sanitizer\TextFieldSanitizer;
-class InputNumberField extends \DropshippingXmlVendor\WPDesk\Forms\Field\BasicField
-{
-    public function __construct()
-    {
-        parent::__construct();
-        $this->set_default_value('');
-        $this->set_attribute('type', 'number');
-    }
-    public function get_sanitizer()
-    {
-        return new \DropshippingXmlVendor\WPDesk\Forms\Sanitizer\TextFieldSanitizer();
-    }
-    public function get_template_name()
-    {
-        return 'input-number';
-    }
+use WPDesk\Forms\Sanitizer\TextFieldSanitizer;
+
+class InputNumberField extends BasicField {
+	public function __construct() {
+		parent::__construct();
