# Custom Fields - How it works

{% hint style="info" %}
A single attribute can use up to 10 custom fields.
{% endhint %}

Custom fields are a way to add extra information to your attributes of type select or multiselect. You can create up to 10 custom fields per attribute, and choose from four different types of custom fields: 

* Image
* Text
* Textarea
* Textarea RTE. 

To create a custom field, follow these steps:

* Edit or [create ](/product-design/attributes/create-a-new-attribute.md)an attribute of type select or multiselect.
* Go to the “*Custom fields*” tab.

* Type a name for your custom field in the “*Custom field code*” input field. This name should be unique and descriptive.
* Choose a custom field type from the drop-down list. The type determines the format and input options for your custom field.
* Click on the “+ Add” button to create the custom field.
* Repeat steps 3 to 5 for each custom field you want to create.

{% hint style="info" %}
Custom fields cannot be edited, you must delete your custom fields and then create a new one if needed.
{% endhint %}

After you create a custom field, you can see it in the “Options” tab, where you can edit its value or values simply by double-clicking on it.

The input field will depend on the type of the custom field. For example, if the custom field type is Image, you can add an image file. If the custom field type is Textarea RTE, you can use the rich text editor to format your text.

* Click on the “Save changes” button to save the changes.
