Customization

Template

Templates are used to create custom card layout as per the user convenient. HTML templates can be specified in the template property of the [kanbancard-settings] as an ID of the template’s HTML element.

You can use JsRender syntax in the template. For more information about JsRender syntax, please refer this link.

The following code example describes the above behavior.
