adapt-contrib-narrative

Narrative is a presentation component bundled with the Adapt framework.

Narrative displays items (or slides) that present an image and text side-by-side. Left and right navigation controls allow the learner to progress horizontally through the items. Optional text may precede it. Useful for detailing a sequential process. On mobile devices, the narrative text is collapsed above the image.

Visit the Narrative wiki for more information about its functionality and for explanations of key properties.

##Installation

As one of Adapt's core components, Narrative is included with the installation of the Adapt framework and the installation of the Adapt authoring tool.

• If Narrative has been uninstalled from the Adapt framework, it may be reinstalled. With the Adapt CLI installed, run the following from the command line:
  adapt install adapt-contrib-narrative

  Alternatively, this component can also be installed by adding the following line of code to the adapt.json file:
  "adapt-contrib-narrative": "*"
  Then running the command:
  adapt install
  (This second method will reinstall all plug-ins listed in adapt.json.)

• If Narrative has been uninstalled from the Adapt authoring tool, it may be reinstalled using the Plug-in Manager.

Settings Overview

The attributes listed below are used in components.json to configure Narrative, and are properly formatted as JSON in example.json. Visit the Narrative wiki for more information about how they appear in the authoring tool.

Attributes

core model attributes: These are inherited by every Adapt component. Read more.

_component (string): This value must be: narrative.

_classes (string): CSS class name to be applied to Narrative’s containing div. The class must be predefined in one of the Less files. Separate multiple classes with a space.

_layout (string): This defines the horizontal position of the component in the block. Acceptable values are full, left or right; however, full is typically the only option used as left or right do not allow much room for the component to display.

instruction (string): This optional text appears above the component. It is frequently used to guide the learner’s interaction with the component.

mobileInstruction (string): This is optional instruction text that will be shown when viewed on mobile. It may be used to guide the learner’s interaction with the component.

_hasNavigationInTextArea (boolean): Determines the location of the arrows (icons) used to navigate from slide to slide. Navigation can overlay the image or the text. Set to true to have the navigation controls appear in the text region.

_setCompletionOn (string): This value determines when the component registers as complete. Acceptable values are "allItems" and "inview". "allItems" requires the learner to navigate to each slide. "inview" requires the Narrative component to enter the view port completely, top and bottom.

_items (array): Multiple items may be created. Each item represents one slide and contains values for the narrative (title, body), the image (_graphic), and the slide's header when viewed on a mobile device (_strapLine).

title (string): This value is the title for this narrative element.

body (string): This is the main text for this narrative element.

_graphic (object): The image that appears next to the narrative text. It contains values for src and alt.

src (string): File name (including path) of the image. Path should be relative to the src folder (e.g.,course/en/images/origami-menu-two.jpg).

alt (string): This text becomes the image’s alt attribute.

strapline (string): This text is displayed as a title above the image when Adapt.device.screenSize is small (i.e., when viewed on mobile devices).

Accessibility

Narrative has been assigned a label using the aria-label attribute: ariaRegion. This label is not a visible element. It is utilized by assistive technology such as screen readers. Should the region's text need to be customised, it can be found within the globals object in properties.schema.

Limitations
