Text List

The Alexa text list template (AlexaTextList) displays a scrolling list of text-based list items. This is a full-screen template that can include the header and background. You provide a set of text-based items to display in the list. You can configure the appearance of the list, such as including dividers and whether items should be numbered. You can also provide the command to run when a user selects an item from the list. You can configure the list to let users swipe items.

Provide the list items

The AlexaTextList layout expects an array of items in the listItems property. Each item is an object with the properties defined in the AlexaTextListItem or AlexaSwipeToAction responsive component.

For example, you could define an array of items like this:

{
  "listItems": [
    {
      "primaryText": "First item primary text",
      "secondaryText": "This is the secondary text",
      "secondaryTextPosition": "bottom",
      "tertiaryText": "This is the tertiary text",
      "tertiaryTextPosition": "bottom",
      "ratingNumber": 2,
      "imageThumbnailSource": "https://d2o906d8ln7ui1.cloudfront.net/images/md_brie.png",
      "hideOrdinal": true,
      "touchForward": true
    },
    {
      "primaryText": "Second item in the list.",
      "secondaryText": "Secondary text for the second item",
      "imageThumbnailSource": "https://d2o906d8ln7ui1.cloudfront.net/images/md_gruyere.png",
      "tertiaryText": "Tertiary text",
      "tertiaryTextPosition": "bottom",
      "ratingNumber": 0
    },
    {
      "primaryText": "Third item in the list.",
      "imageThumbnailSource": "https://d2o906d8ln7ui1.cloudfront.net/images/sm_blue.png"
    },
    {
      "primaryText": "Fourth item in the list"
    },
    {
      "primaryText": "Fifth item in the list"
    },
    {
      "primaryText": "This list might have many more items"
    }
  ]
}

You can provide this array in the listItems array parameter of AlexaTextList, or in a separate data source.

The specific list item parameters available depends on the version of AlexaTextListItem. For example, the properties to display a rating require the 1.2.0 or later version of the alexa-layouts package. For the full set of properties, see:

Specify the action for each list item

AlexaTextList is interactive. Users can select items on the list. Set the primaryAction property to the command you want to run when the user selects an item.

When you set primaryAction on the AlexaTextList component, AlexaTextList passes the command to each item on the list.

To override command for an individual list item, set the primaryAction property on the list item itself.

The following example shows how you to use the SendEvent command to send your skill a UserEvent request. This passes the number representing the selected item as part of the SendEvent.arguments array.

{
  "primaryAction": {
    "type": "SendEvent",
    "arguments": [
      "ListItemSelected",
      "${ordinal}"
    ]
  }
}

Let users swipe the list items

To let users swipe the list items to take actions, set the swipeDirection property to left or right. Then, set the other swipe-related properties as needed. These properties correspond to AlexaSwipeToAction properties:

  • swipeActionIcon
  • swipeActionIconType
  • swipeActionIconForeground
  • swipeActionIconBackground
  • onSwipeMove
  • onSwipeDone
  • optionsButton1Text
  • optionsButton1Command
  • optionsButton2Text
  • optionsButton2Command
