-## Details
-
-The picker shows the user a menu of sorting options (which could be data columns to sort on
-alphabetical vs numerical search, etc) and the choice of ascending vs descending sort order.
-Note that picker only implements the menu, so you are responsible for implementing the sorting
-options yourself.
-
-The `options` property contains an array of any objects that expose the following properties:
-
-```ts
-{
-    key: string;
-    label: string;
-}
-```
-
-The `key` is an identifying value and the `label` is the text that the user will see in the
-picker. The selected `key` is reported by the `change` event, which passes an object like the
-following as its parameter:
-
-```ts
-{
-    key: string,
-    ascending: boolean
-}
-```
