Traits

Traits define the type and capabilities of your Custom Elements. They tell HELIO where and how your element can be used.

Common Traits Include:

• traits.Control can be added to a Dashboard Page, a Dashboard Widget, or a Parameter Page.
• traits.Widget can be placed on a Dashboard Page.
• traits.Page let you create pages that take up the whole viewport of your HMI and will be made available in the main navigation.

In general elements can have multiple traits, allowing them to be used in different contexts. But traits.Widget and traits.Control cannot be used together. Therefore, an element cannot possess both of these characteristics; it is either a widget or a control.
