Pagination

Used to let users navigate through content broken down into pages. Usually paired with tables.

Use Pagination to let users navigate through content broken down into pages. Usually paired with tables, but works with other types of page content.

Usage

When to use

  • To break down large content into pages. Usually paired with tables, but works with other types of page content.

When not to use

  • As a navigation control for a flow or to pair with a stepper, i.e. for a guide, tutorial, or setup flow.
  • As a controller to switch between multiple views. Use Tabs instead.

Numbered vs Compact

Cursor and offset are the most common types of pagination. Currently, most HashiCorp products use cursor-based navigation.

Cursor navigation allows users to navigate to the next or previous set of records no matter where the user is located within the dataset (record 1 or 300). With this type of pagination, the system doesn’t know which page the current page is and can’t show page numbers (1, 2, 3, etc…). If your product supports it, you should use compact pagination.

Offset or page-based pagination allows you to divide datasets into pages, letting users navigate to any particular page. If your product supports it, you can use either numbered or compact pagination. In most cases, the numbered pagination provides a better user experience. It allows users to jump between pages and always return to the first page or go to the last page without navigating through the pages manually.

Numbered pagination example

  • Supported by offset (page-based) pagination.

Compact pagination example

  • Supported by offset and cursor based pagination.

We strongly suggest that you talk to your engineering team to see which pagination variant is right for your project.

Spacing

  • When using the pagination bar, the container should be flush on the left & right with the content.
  • When using the pagination, the component should be center aligned with the content it relates to.
  • Make sure there’s enough distance and breathing room between the pagination and unrelated content (e.g. another section below it), so it’s clear what content the pagination is paired with.

When pairing the pagination or pagination bar with tables, we recommend:

  • 16px between the pagination or pagination bar and the content it relates to.

Spacing for pagination paired with tables

When pairing with content which is not contained (e.g. cards, lists), we recommend:

  • At least 16px for consistency. If your product uses a scale where the spacing between elements tends to be higher or lower, or the paginated content looks optically loose or tight to the component, increase or decrease the spacing accordingly.

Compact vs Numbered Pagination

There are two different variants of the Pagination component (with different ways to invoke them) built to cover different use cases, contexts, and designs you may need them for.

This differentiation is necessary to cover both use cases of pagination for a list with a known number of elements (i.e., "numbered") and one in which this information is not available or is cursor-based (i.e., "compact").

In the first one, the user is presented with a list of navigation controls ("prev/next" and "page numbers" to go directly to a specific page) and other optional UI elements; in the second, much simpler one, the user is presented with only the "prev/next" controls.

When pagination is invoked directly using one of these two components, it will automatically:

  • provide the correct responsive layout for the entire Pagination and its sub-parts.
  • manage the "current page" status across the different sub-components it’s made of (based on the arguments provided to it and its children).
  • when one of the "navigation controls" is clicked, a callback function (if provided) is called, and a route (if provided) update is triggered.
  • when the "page size" is changed via the provided selector, it will automatically recalculate the total number of pages to display to the user.

Pagination sub-components

If you need more control on the specific Pagination parts, and/or you need to cover a very specific use case, you can use the Pagination sub-elements directly (Pagination::Info/Nav(*)/SizeSelector).

In this case, you will have to take care of different things yourself

  • the organization/layout of the elements on the page.
  • the logic to handle the "current page" status.
  • the logic connecting the different parts (if using Numbered Pagination).

Events handling and routing

As described above, the main Pagination::Numbered and Pagination::Compact components expose an onPageChange callback function, invoked whenever a page change occurs. All the "navigation controls" in this cases are <button> elements that fire an onClick event that calls the onPageChange function.

This means that if you need to update the URL when the user changes the "page" in the Pagination (eg. to add/remove/update some query parameters), you have to do it within the onPageChange callback you provide to the component.

If instead you need to update the URL directly when the user clicks on one of the "navigation control" elements, you have to provide routing parameters (route/query/model/etc) to the component; refer to the "Component API" section below for specifications about these parameters (the APIs are slightly different for the two components).

How to use Numbered Pagination

The basic invocation of Numbered Pagination requires the @totalItems argument to be provided (plus the event/routing handlers, see below):

1–10 of 40
<Hds::Pagination::Numbered @totalItems={{40}} />

By default the Info and SizeSelector sub-components are displayed, and the component takes care of updating the values and the states of the different elements, according to the user interactions with the component.

Extra arguments

It’s possible to customize the Info, Controls, and SizeSelector components by providing additional arguments to them. For more details about these parameters, refer to the "Component API" section.

Below is an example of some of these extra arguments:

1–20
<Hds::Pagination::Numbered
  @totalItems={{40}}
  @showTotalItems={{false}}
  @showSizeSelector={{false}}
  @pageSizes={{array 5 20 60}}
  @currentPageSize={{20}}
/>

Example of custom label text for Pagination::SizeSelector

1–10 of 40
<Hds::Pagination::Numbered
  @totalItems={{40}}
  @sizeSelectorLabel="Per page"
/>

Truncation

When there is a large number of items and consequently the number of pages is also large, by default the component automatically "truncates" the number of visible pages (using "ellipses"):

1–10 of 120
<Hds::Pagination::Numbered
  @totalItems={{120}}
/>

If necessary, it’s possible to disable this functionality using the @isTruncated argument:

1–10 of 120
<Hds::Pagination::Numbered
  @totalItems={{120}}
  @isTruncated={{false}}
/>

Events handling

The component exposes two callback functions that can be used to respond to specific events:

1–10 of 40
<Hds::Pagination::Numbered
  @totalItems={{40}}
  @onPageChange={{this.handlePageChange}}
  @onPageSizeChange={{this.handlePageSizeChange}}
/>

The first onPageChange function is invoked when a user interacts with a navigation control ("prev/next" or "page number") and so can be used to respond to a "page" change (eg. updating the list of items in the page and/or updating the routing/URL).

The second onPageSizeChange function is invoked when a user interacts with the "size selector" and so can be used to respond to a "page size" change (eg. updating the number of items listed in the page, updating the routing/URL, and/or updating other elements in the page).

Routing/URL updates

If you want the Pagination to change the URL of the page directly (eg. updating the query parameters) you need to pass the routing parameters to the component:

1–5 of 39
<Hds::Pagination::Numbered
  @totalItems={{this.demoTotalItems}}
  @currentPage={{this.demoCurrentPage}}
  @pageSizes={{this.demoPageSizes}}
  @currentPageSize={{this.demoCurrentPageSize}}
  @route={{this.demoRouteName}}
  @queryFunction={{this.demoQueryFunctionNumbered}}
/>

where the @queryFunction function will be something like this:

get demoQueryFunctionNumbered() {
  return (page, pageSize) => {
    return {
      demoCurrentPage: page,
      demoCurrentPageSize: pageSize,
      demoExtraParam: 'hello',
    };
  };
}

When the routing parameters are provided, the "navigation controls" are rendered as links and if the user clicks on one of them the page URL is automatically updated. This means that the component’s state is persisted outside of the component and so its whole state must be "controlled" by the consumer’s code (otherwise there would be conflicting states).

In this case, the component doesn’t update its internal "state" but the value of the state variables (eg. currentPage/currentPageSize) is always determined by the consumer’s controller code via the component’s arguments (usually, they are directly connected to the query parameters in the URL).

The reason for using a consumer-side function to determine the query argument is because it’s dynamic (it depends on the value of the page variable) and gives consumers the ability to specify their own query parameters (which will likely differ case by case).

Even if the Pagination is based on routing, the onPageChange/onPageSizeChange callbacks are still available and can be used to respond to the users’ actions (eg. for logging, tracking, etc.).

Below you can find an example of an integration between the sortable Table component and the Pagination::Numbered component that uses query parameters in the URL to preserve the UI state:
