# Enum BaseTemplate

OptimaJet.Workflow.Core.BaseTemplate

Specifies the data model used by the workflow designer to edit a custom activity.

Namespace: [OptimaJet.Workflow.Core](https://api.workflowengine.io/core/OptimaJet.Workflow.Core/)

```csharp
public enum BaseTemplate
```

## Fields

`Activity = 0` 

Treats the template specified by [FormBase.Template](https://api.workflowengine.io/core/OptimaJet.Workflow.Core/FormBase/) as an activity editor and supplies the complete [ActivityDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActivityDefinition/) to it.

### Remarks

Use this value for custom templates based on the standard activity editor that edit native activity fields, such as implementations, timeouts, or outgoing transitions.

`JsonForm = 1` 

Treats the editor as a parameter form populated from activity annotations.

### Remarks

If [FormBase.Template](https://api.workflowengine.io/core/OptimaJet.Workflow.Core/FormBase/) is not specified, the designer uses its generic JSON form and creates controls from [FormBase.Parameters](https://api.workflowengine.io/core/OptimaJet.Workflow.Core/FormBase/). The entered values are saved according to [ActivityBase.SaveToAnnotationsPolicy](https://api.workflowengine.io/core/OptimaJet.Workflow.Core/ActivityBase/).
