Inventory Tracking

Inventory Tracking example

Labeling Configuration

<View>
  <View style="display:flex;justify-content:center">
    <PolygonLabels name="objects" toName="image" value="$objects"/>
  </View>
  <Image name="image" value="$image"/>
</View>

Let’s get through configuration. View is used only for layout purposes. The main thing here is the value in PolygonLabels, it allows us to load labels dynamically for every task from related array in task data, one Label per item. Every parameter from such item in data will be present as parameter in generated Label tag.

Also there is new html parameter for Label tag which allows to display rich content as label. This content should be html-escaped:

  • <&lt;
  • "&quot;
  • >&gt;
  • etc.

Stored value still comes from value parameter, it’s required.

You can also use usual static Labels inside Labels tag in combination with dynamic ones — static labels will be displayed first.

Example data

We use value=$objects so we should set objects field in task data as the source for generated labels, every item contains parameters for such tags, these parameters can be different for every label, the only required is value. html content should be string-escaped, so it’s better to use single quotes here.
