DropdownSection

children

REQUIRED

node|function

This component can render either declaratively, by directly passing a set of children or virtualized, by passing a render callback (function as children).The only items allowed inside (or returned by the render callback) are of type <DropdownItem>.The recommendation is to use the render callback when a large number of items is provided, since the item list will be virtualized by the component, thus increasing the performance.

className

string

Appends class names to the component.Should be used only for positioning and spacing purposes.

items

array

Items to render, in the shape of a list of objects. Usually, each item in the items array contains the required data to generate the corresponding <DropdownItem>.This prop is required when rendering items with the render callback (function as children).

onLoadMore

function

Callback fired when more items must be loaded. This happens when you're lazy loading the items and the items that are about to render cannot be found in the items array.This callback should be used to fetch/load the missing items from the backend or other sources.The returned Promise should be resolved once item data has finished loading. It will be used to determine when to refresh the list with the newly-loaded data. This callback may be called multiple times in reaction to a single scroll event.

rowCount

number

Number of rows.By default it's equal to length of array passed in the items prop.You should specify the rowCount when you know the total number of items but you want to lazy load them while scrolling.

style

object

Inline style for custom styling.Should be used only for positioning and spacing purposes.

testId

string

Adds a data-test-id attribute. Use it to target the component in unit and E2E tests.For a test id to be valid, prefix it with your nerdpack id, followed up by a dot.For example, my-nerdpack.some-element.Note: You might not see data-test-id attributes as they are removed from the DOM, to debug them pass a e2e-test query parameter to the URL.

title

string

Section title.
