IsContainer Search Criterion

The `IsContainer` Search Criterion 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

You can use this Search Criterion over the REST API, in the payload of the [`POST /views`](https://doc.ibexa.co/en/saas/api/rest_api/rest_api_reference/rest_api_reference.html#tag/Views/operation/ibexa.rest.views.create) request:

**XML**

```xml
<Query>
    <Filter>
        <IsContainerCriterion>true</IsContainerCriterion>
    </Filter>
</Query>
```

**JSON**

```json
"Query": {
    "Filter": {
        "IsContainerCriterion": true
    }
}
```
