+# IsContainer Criterion
+
+The [`IsContainer` Search Criterion](/api/php_api/php_api_reference/classes/Ibexa-Contracts-Core-Repository-Values-Content-Query-Criterion-IsContainer.html) searches for content items based on whether they are containers (i.e., can contain other content items).
+
+## Arguments
+
+- `value` – boolean (optional, default: `true`). If `true`, searches for content that is a container. If `false`, searches for content that is not a container.
+
+## Example
+
+### PHP
+
+```php
+$query->query = new Criterion\IsContainer(); // Finds containers
+$query->query = new Criterion\IsContainer(false); // Finds non-containers
+```
