Good afternoon. I was wondering. I am in need of creating a custom field type. Even following the tutorial it shows all the way up to building the new field. It seems to be working fine but I do not really know how to use it after that. Not in code and I cant seem to find it anywhere in the back office.

I can from any c# class do the following:  
var test = new FieldTypes.CustomTextFieldTypeMetadata();  
However attaching it to a template is another matter. I realise I am missing something here. Any ideas?

Litium version: 7.2.3

You need to create a field definition using your custom field type, then you can add it to a template. If you go to the Settings \> the module you want to use the field in \> Fields, you can create the field by clicking New and selecting your custom field type in the list. Then you can go to Field Templates, edit a template and add the newly created field.

Programmatically, you create the field with something like (inject the services in the constructor):

```auto
var field = new FieldDefinition<ProductArea>("MyField", "CustomFieldTypeName")
{
	CanBeGridColumn = false,
	CanBeGridFilter = false,
	MultiCulture = false,
};

using (_securityContextService.ActAsSystem())
{
	_fieldDefinitionService.Create(field);
}

```

Then it depends on if you want to create a new template or add it to an existing one. In the Accelerator you can check out Definitions for some more examples.

You can also look att

> ProductsDefinitionSetup.cs

to see how the initial setup is created.
