The list widget shows a sorted collection of features or rows. The list can include all of the features from the data source or can be limited to display only a certain number of features. For example, a list widget can be configured to detail all the buses in a municipal transportation district and sort them by their remaining fuel, with those that have the least amount of fuel at the top of the list.
listed features sort themselves based on updated
information. In an emergency management scenario, the list could be configured to show the currently open evacuation shelters and their remaining capacities. In addition, the list widget can display items based on a selection. If the selection changes, the list re-sorts itself. Features may also appear and disappear from the list when only a
subset of features from the data source is included.
When configuring how the feature is displayed, you can include an icon to represent the feature in the list, such as whether an evacuation center is a medical facility or a school. You can also include additional information for each item in the list, which can be static or can be obtained from field values. In the following example, Capacity displays before the field values:
Feature actions add display and navigation functions to individual features in the widget. If the widget's
data source is a layer in a map, you can zoom the map to the feature, flash it on the map, select it
on the map, or have the map follow the feature as it moves automatically.
The list widget can be the data source for another widget. When configuring other widgets, you can set either the top item or the selected item in the list to be the data source. For example, using the information in the list, you can configure a gauge to sum the evacuees from all the shelters to monitor when the city's evacuation center capacity has been exceeded.
