Пожалуйста, используется данный сниппет: <?php $id = $modx->resource->id; $opKey = 'msOption'; $copKey = 'msCategoryOption'; $filters

= explode(',', $scriptProperties['filters']);
$tplRow = $scriptProperties['tplFilter.row'];
$tplOuter = $scriptProperties['tplFilter.outer'];

$filterKeys = [];
foreach($filters as $filter) {
$filterKey = reset(explode(':', end(explode('|', $filter))));
$filterKeys[$filterKey] = $filterKey;

}

$q = $modx->newQuery($copKey);
$q->select(array(
"{$copKey}.category_id",
"{$copKey}.option_id",
"{$opKey}.key"
));
$q->where(["{$copKey}.category_id" => $id]);
$q->leftJoin($opKey, $opKey, "{$copKey}.option_id = {$opKey}.id");


$q->prepare();
$q->stmt->execute();
$options = $q->stmt->fetchAll(PDO::FETCH_ASSOC);

$_options = [];

if(count($exclude) > 0) {
foreach ($options as $key => $option) {
if (array_search($option['key'], $exclude) > -1) {
unset($options[$key]);
}
}
}

foreach ($options as $option) {
if(!array_key_exists($option['key'], $filterKeys)) {
switch($option['type']) {
case 'checkbox':
$filter = ':boolean';
break;
case 'numberfield':
$filter = ':number';
break;
default:
$filter = '';
break;
}

if ($option['type'] == 'checkbox') {
$filter = ':boolean';
}

$_options[] = 'msoption|' . $option['key'] . $filter;
$scriptProperties['tplFilter.outer.msoption|' . $option['key']] = $tplOuter;
$scriptProperties['tplFilter.row.msoption|' . $option['key']] = $tplRow;
}
}
$scriptProperties['filters'] = implode(',', array_merge($_options, $filters));

return $modx->runSnippet('mFilter2@filter', $scriptProperties);

вот вызов сниппета

{'!mFilter3' | snippet : [
'includeThumbs' => 'standard',

Сниппет странный.. Попробуй с дефолтным

Тотже результат
