Pagination
Pagination allows users to navigate through large amounts of content or data divided across multiple pages while making it clear that more pages exist.
Anatomy
- Page Numbers: Each page has its own page number. All page numbers inherit styling and interactions from our Icon Only Primary Button Variant.
- Navigational Controls: Allow users to navigate through available pages. These controls inherit styling and interactions from our Icon Only Tertiary Button. Previous/Next uses Small Chevron System Icon and First/Last uses Chevron x2 Small System Icon.
- Input w/ Label: Shows a box adjacent to the pagination bar where a page can be entered and is submitted when 'Enter' key is pressed. Enables users to jump to specific page. Input uses the Canvas Text Input with browser-specific numeric input override.
- Additional Details: Communicates the number of pages and total number of items. Page numbers are separated by an en dash. The word “pages” is customizable.
Pagination is a highly configurable component so we’ve intentionally built each piece of this component separately so you may compose it in a variety of ways.
Usage Guidance
- Pagination is a highly configurable navigation component composed of the following elements:
- Page Numbers: Provide context about what page the user is on in relation to other pages.
- Page Navigation: Navigational controls allow users to navigate back or forward through pages. If applicable, they are also able to jump to the first or last page.
- Numeric Input: Enables users to jump to a specific page.
- Label: Communicates the number of pages and total number of items. The word “items” is customizable.
- Although the component is typically placed below the corresponding content or data, there is flexibility on placement depending on your use case.
- Pagination is typically used with Tables.
- In responsive experiences, Pagination condenses to its most basic elements (Left/Right Controls, Current Page Number).
When to Use
- To divide large quantities of data or content into chunks.
- To improve the loading performance of a system.
- To make user comprehension of data/content less overwhelming.
- To enable all users to navigate to through pages or locate a specific page number.
- To show how many pages of content there are and how many results have been returned.
Best Practices
- Display at least one way for users to navigate through pages. If possible, provide more than one option (eg. Previous/Next controls and a Numeric Input).
- Display the Current Page to provide awareness of location in relation to the other pages.
- If feasible, display additional details (number of pages and total number of items) to communicate even more context about the content or data the user is paging through.
Each element of Pagination has been built separately so you may compose it in a variety of ways. How you decide to put this component together will likely depend on the reality of the technical constraints that exist and your user needs.
Below are some examples of how you can configure Pagination based on screen size or technical considerations. These recommendations are not exhaustive.
Based on Screen Size:
- For smaller screens, it’s recommended to show page navigation controls with no more than 3 pages.
- For larger screens, you can show up to 5 pages, both types of page navigation controls, and a numeric input with additional details.
Based on Technical Considerations:
- If your API is unable to return a total page number, we recommend showing the Previous/Next page navigation controls, the Current Page Number, and up to 4 other Page Numbers (if possible).
- If your API is able to return a known number of pages, composability options are endless. You can essentially pair any combination of elements together to create a solution that is best for your use case.
Examples
Basic Example
Pagination
includes a container Pagination
component and a number of subcomponents which can be
composed in a variety of ways.
In this example, we set up a basic Pagination
component with the default range of five pages, as
well as step controls (Pagination.StepToPreviousButton
and Pagination.StepToNextButton
) that
allow you to move to the previous page or the next page.
Note that you must include Pagination.AdditionalDetails
to meet accessibility standards (with one
exception, see Pagination.AdditionalDetails
for more information).
It is an aria-live
region that announces the current page update to screen readers. If you wish to
prevent it from displaying (as we've done in the remaining examples), you may set its
shouldHideDetails
prop to true
. The visually hidden region will still be accessible to screen
readers.
Hoisted Model
By default, Pagination
will create and use its own model internally. Alternatively, you
may configure your own model with usePaginationModel
and pass it to Pagination
via the model
prop. This pattern is referred to as
hoisting the model
and provides direct access to its state
and events
outside of the Pagination
component.
In this example, we set up external observation of the model state and create an external button to trigger an event to change the current page.
Jump Controls
This example adds jump controls (Pagination.JumpToFirstButton
and Pagination.JumpToLastButton
)
that allow you to skip to the first and last pages in the range.
GoTo Form
This example adds a form (Pagination.GoToForm
) that allows you to skip to a specific page within
the range.
Right-to-Left (RTL)
Pagination
supports right-to-left languages when specified in the CanvasProvider
theme
.
Custom Range
This example uses a custom range that allows you to control the width of the component.
Responsive Range
In some situations, you might want to adjust Pagination's range based on the width of the container.
You can use useResizeObserver
to accomplish this as in the example below.
Component API
Pagination
Pagination
is a container component rendered as a <nav>
element that is responsible for creating
a PaginationModel
and sharing it with its subcomponents using React context.
<Paginationaria-label="Pagination"lastPage={100}initialCurrentPage={6}rangeSize={3}onPageChange={pageNumber => console.log(pageNumber)}>{Child components}</Pagination>
Alternatively, you may pass in a model using the hoisted model pattern.
const model = usePaginationModel({lastPage: 100,initialCurrentPage: 6,rangeSize: 3,onPageChange: pageNumber => console.log(pageNumber),});return (<Pagination aria-label="Pagination" model={model}>{Child components}</Pagination>);
Layout Component
Pagination
supports all props from thelayout component.
Props
Props extend from nav. Changing the as
prop will change the element interface.
Name | Type | Description | Default |
---|---|---|---|
aria-label | string | ||
children | ReactNode | ||
lastPage | number | ||
firstPage | number | ||
initialCurrentPage | number | ||
rangeSize | number | ||
model |
| ||
onPageChange | (pageNumber: number) => void | ||
as | React.ElementType | Optional override of the default element used by the component. Any valid tag or Component. If you provided a Component, this component should forward the ref using Note: Not all elements make sense and some elements may cause accessibility issues. Change this value with care. | nav |
ref | React.Ref<R = nav> | Optional ref. If the component represents an element, this ref will be a reference to the real DOM element of the component. If |
Pagination.Controls
Pagination.Controls
provides proper alignment and spacing between elements inside
Pagination
. It does not handle any internal business logic or state.
<Pagination.Controls>{Child components}</Pagination.Controls>
Props
Props extend from div. Changing the as
prop will change the element interface.
Name | Type | Description | Default |
---|---|---|---|
children | React.ReactNode | ||
as | React.ElementType | Optional override of the default element used by the component. Any valid tag or Component. If you provided a Component, this component should forward the ref using Note: Not all elements make sense and some elements may cause accessibility issues. Change this value with care. | div |
ref | React.Ref<R = div> | Optional ref. If the component represents an element, this ref will be a reference to the real DOM element of the component. If |

Model
If Pagination
was stripped of all its markup, attributes, and styling, what would remain is the
model. The model is an
object composed of two parts: state
which describes the current snapshot in time of the component
and events
which describes events that can be sent to the model.
By default, Pagination
will create a model and share it internally with its subcomponents using
React context. You may subscribe to PaginationContext
if you wish to create a custom subcomponent
for your implementation. Here's a simple example.
import * as React from 'react';import {Pagination, PaginationContext} from '@workday/canvas-kit-react/pagination';const CustomButton = (props: React.HTMLAttributes<HTMLButtonElement>) => {const model = React.useContext(PaginationContext);const handleClick = (e: React.MouseEvent<HTMLButtonElement, MouseEvent>) => {// If onClick is provided, pass the event alongprops.onClick?.(e);model.events.goTo(10);};return (<button onClick={handleClick} {...props}>Go To Page 10</button>);};export const CustomPagination = () => {return (<Pagination aria-label="Pagination" lastPage={20}><CustomButton aria-label="Page 10" />{/* Other subcomponents */}</Pagination>);};
Alternatively, if you need direct access to the model's state
and events
outside of the
Pagination
component, you may configure your own model with usePaginationModel
and pass it to
Pagination
via a pattern called
hoisting the model.
const model = usePaginationModel({lastPage,onPageChange: number => console.log(number),});<Pagination aria-label="Pagination" model={model}>{/* Child components */}</Pagination>;
usePaginationModel
usePaginationModel
accepts a configuration object with the following properties and returns a
PaginationModel
with state
and events
properties.
Utilities
getLastPage
getLastPage
This function takes the number of results per page and the total count of results and returns the last page number. Here's an example:
Given there are 10 results per page, and there are 128 total results, the function will return 13.
const lastPage = getLastPage(10, 128); //=> 13
(
resultCount: number,
totalCount: number
) => number
getRangeMin
getRangeMin
This function takes the pagination range and returns its minimum value. Here's an example:
Given the pagination range is 1-5, the function will return 1.
const range = [1, 2, 3, 4, 5];const rangeMin = getRangeMin(range); //=> 1
(range: number[]) => number
getRangeMax
getRangeMax
This function takes the pagination range and returns its maximum value. Here's an example:
Given the pagination range is 1-5, the function will return 5.
const range = [1, 2, 3, 4, 5];const rangeMin = getRangeMax(range); //=> 5
(range: number[]) => number
getVisibleResultsMin
getVisibleResultsMin
This function takes the current page, and number of results per page, and returns the minimum value for that page. Here's an example:
Given there are 10 results per page, and the current page is 5, the function will return 41.
const pageMin = getVisibleResultsMin(5, 10); //=> 41
(
currentPage: number,
resultCount: number
) => number
getVisibleResultsMax
getVisibleResultsMax
This function takes the current page, number of results per page, and the total number of results, and returns the maximum value for that page. Here's an example:
Given there are 10 results per page, the current page is 5, and there are 42 results total, the function will return 42.
const currentPage = 5;const resultCount = 10;const totalCount = 42;const pageMax = getVisibleResultsMax(currentPage, resultCount, totalCount); //=> 42
(
currentPage: number,
resultCount: number,
totalCount: number
) => number
Accessibility Guidelines
- The actively selected page in the component is conveyed to assistive technology by setting aria-current="page" on the button element.
- Icon only Primary/Secondary/Tertiary buttons inside the component must have accessible names for assistive technologies. For example: “Next,” “Previous,” “First,” “Last.”
- Pagination buttons can be focused with the keyboard and actioned with 'Enter' or 'Spacebar' keys. Please note that aria-disabled is used in this component, so buttons with this attribute will not be actionable using 'Enter' or 'Spacebar'.
- If the browser does not reload a full page of content and change the page title after interacting with pagination, non-visual screen reader users will need to be alerted of the new content revealed on screen. This can be accomplished by setting keyboard focus at the top of the updated content.
- The additional details variant (X - Y of Z items) is inside of a live region and designed to be announced by assistive technologies in real-time.
- For more information on colors and contrast, check out our article on Accessible Color.
- For more information on non-text content, check out our article on Alt-Text and Non-Text Content Labels.
Content Guidelines
- If customizing the label of the total number of items, use a word that accurately describes the items that are being shown.
- Placement of the label is flexible.
