# Edit a Container

{% hint style="warning" %}
It is only possible to edit your container once the DNS A Record and HTML Code are verified.
{% endhint %}

You can easily edit your container’s configuration by going to your **Containers** menu and click on **Edit**:

<figure><img src="/files/zexgyi5C3UrUUZFg13bt" alt=""><figcaption></figcaption></figure>

You are able to change the following fields:

**Basic Settings:**

* **Container name** – A descriptive name for your container.
* *Optional field:* **Consentbar (CMP)** – Select from the list of supported consent bars.

{% hint style="warning" %}
Once the container is created, you can not change the **website domain**.
{% endhint %}

**Advanced Settings (Optional):**

* **Preview URL** – Set a custom URL instead of the website domain for the container configuration preview session. If this field is left empty, the **website domain** configured on the basic settings will be used.
* **Main Domain Cookie** — This feature allows you to configure whether first-party identifiers (e.g., JENTIS User-ID) are implemented at your website’s main domain or subdomain level in your containers. This enables the identification of users across the main domain and its subdomains. For more information, read.

Once you change any of these fields, click **Save** and **Publish** your container again.
