# Template - UDT Parameter
>
## UDTs in Templates
User Defined Types (UDT) parameters are properties that you can bind the template components to. Since the UDT parameter is a Custom property that encapsulates the UDT tags and some meta properties you can access all this information through a custom property.
### To Add a Component to the Template and Bind it to Parts of UDT
1. Start with a blank template.
2. Add components to the template.
3. Create a **Custom** property on the template's Root Container, and make the Custom property's **Type** a **User Defined** type instead of a **Standard** data type and click **OK**.

4. Select a component on the template, in the component's **Property Editor**, click the binding icon next to the property that you want to influence.
5. Select the **Property** binding and choose the tag from the UDT that you would like the binding to occur and and click **OK**.
