Migrating from terra-clinical-item-collection v1 to v2

The following sections describe how to migrate from using the ItemCollection API provided in terra-clinical-item-collection v1 to the new API provided in the v2 release. The v2 release introduces new API and now allows for static and selectable Item Collection rendering. These changes allow for easier implementation, as well as more flexibility in use and future enhancements.

Behavior Changes

Added/Changed Behavior

Allows for either static and selectable implementation
Supports Children API which introduces the ItemCollection.Item component
OnSelect returns the event and child key for onClicks and onKeyDowns
Exports the following components: ItemCollection.Item, ItemCollection.Display and ItemCollection.Comment
Table layout is no longer dependent on first collection row #213

If a display is missing, the ItemCollection will allocate space to maintain the provided layout.

Prop Changes

Props Added

children - the Item Collection Items that will flex between either a list item or a table row.
hasStartAccessory - indicates if space should be allocated for a start accessory.
numberOfDisplays - the number of displays the Item Collection should allocate space for (maximum of 8).
hasComment - indicates if space should be allocated for a comment.
hasEndAccessory - indicates if space should be allocated for an end accessory.
onSelect - the callback function that is assigned as to a child's onClick and onKeyDown callback if the child isSelectable. The first parameter returned is the event and the second parameter is the child key.

Props Changed

rows - replaced with children prop.
onChange - replaced with onSelect prop.
listStyles - flattened and replaced with isListDivided prop. Additionally, the Item Collection no longer provides chevron styles as chevrons are intended for single-selectable lists only to indicate clicking the item will reveal more information. This behavior is not currently present in selectable tables.
tableStyles - flattened and replaced with isTablePadded and isTableStriped.

ItemCollection.Item

This component handles the rendering of a list item or table row for the ItemCollection. By default, this would render an ListItem with an ItemView as the content. Else, it will render a TableRow with the element layout order of startAccessory, displays, comment, then endAccessory. This component provides a clean way to represent an item within the item collection, and would not handle missing element logic if used outside of the Item Collection as intended.

Usage

<ItemCollection.Item
  startAccessory={ <Accessory />}
  comment={ <ItemCollection.Comment />}
  endAccessory={ <Accessory />}
  isListItemTruncated
>
  <ItemCollection.Display />
  <ItemCollection.Display />
  <ItemCollection.Display />
</ItemCollection.Item>

Code Migration

Migrating from v1.4 to v2:

   import React from 'react';
-  import ItemView from 'terra-clinical-item-view';
   import ItemCollection from 'terra-clinical-item-collection';

  class OnChangeItemCollection extends React.Component {
    constructor(props) {
      super(props);
-     this.state = { selectedIndex: 2 };
+     this.state = { selectedItemKey: 'key-2' };
      this.handleSelection = this.handleSelection.bind(this);
    }

-    handleSelection(event, selectedIndex) {
-      this.setState({ selectedIndex });
-    }

// Selection logic is not handled by the Item Collection, it only returns the event and child key selected
+  handleSelection(event, selectedItemKey) {
+    if (event.nativeEvent.type === 'click') {
+      this.setState({ selectedItemKey });
+    }
+  }
