About single and multiple slot modes

AlexaRating has two different modes for displaying the rating, set in the ratingSlotMode property:

  • Single – Display a single, static graphic. You can provide the either an AVG or image to display and the width to use for the image.
  • Multiple – Use a numeric rating between 0 and 5, such as "3.5", to dynamically determine the set of graphics that represent the rating. This option uses three different graphics representing the state of each "slot" – full, half, or empty. For example, for a 3.5 rating, this option displays the "full" graphic three times, the "half" graphic once, and finally the "empty" graphic once.

The AlexaRating responsive component includes default "star" graphics for the full, half, and empty states. You can use these or provide your own image or AVG.

The following example displays a 3.5 rating with the default star graphics.

{
  "type": "AlexaRating",
  "ratingSlotPadding": "4dp",
  "ratingSlotMode": "multiple",
  "ratingNumber": 3.5,
  "ratingText": "509 ratings"
}
