4.  Select the card where you want to apply a card template.

    **Note:** A screen may contain more than one card view. For example, a list screen may have an legacy card for the list and another for the form.

5.  Select **Open** button.

    Card builder opens using its current card template.

    **Note:** If you have your screen open in Mobile App Builder, you can also open the template by selecting the **Mobile Card Builder** button.


## What to do next

To change the layout of the elements of your mobile card, see [Mobile Card Builder user interface](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/mobile/mcb-stage-ui.md).
