Paginator. Overview

Preview.

What does the component do?

The paginator divides large amounts of content, e.g. tables or lists, into pages. It shows the current page and provides controls to switch pages. Optionally, users can change the number of entries per page. A compact variant (compact paginator) shows only the current page and the total.

When should the component be used?

  • When many entries should be split into pages.
  • When an alternative to infinite scrolling is needed.
Usage

Rules.

  • For few pages, "Load more" is usually the better solution.
  • When space is limited, e.g. on small screens, use the compact paginator.
  • The paginator needs a label for screen readers (aria-label) that describes what it controls.

Elements.

This component includes several elements that can be used on their own.

  • sbb-compact-paginator
  • sbb-paginator

Documentation.

The <sbb-paginator> is a component which provides navigation for content split across multiple pages,
e.g. a table with many rows. An alternative, more compact variant is available as <sbb-compact-paginator>.

It can be controlled via the following properties:

  • length: the total number of items being paged;
  • pageSize: the number of items per page (default: 10);
  • pageIndex: the index of the current displayed page (default: 0).
<sbb-paginator length="100" page-size="20"></sbb-paginator>

By default, a sbb-mini-button-group with two buttons is displayed,
which allows moving to the previous/next pages.
The positioning of this element relative to the page numbers is set using the pagerPosition property (default: start):

<sbb-paginator length="100" page-size="20" pager-position="end"></sbb-paginator>

Users have the possibility to dynamically change the page size using a dropdown menu;
to do this, consumers must add the pageSizeOptions property, which accepts an array of number
that are set as <sbb-option>'s values within a <sbb-select>.
Consumers must be consistent, so the defined pageSize must be an element of the pageSizeOptions array.
The dropdown menu and the previous / next buttons are facing each other with the page numbers always in the center.

<sbb-paginator length="100" page-size="20" page-size-options="[10, 20, 50]"></sbb-paginator>
Compact Paginator.

An alternative, more compact variant with the same functionality is the <sbb-compact-paginator>.
In contrast to the <sbb-paginator>, it displays only the current page and the total number of pages
together with the <sbb-mini-button-group> to move to previous or next page.

<sbb-compact-paginator length="100" page-size="20"></sbb-compact-paginator>
States.

The component can be disabled by using the disabled property.

<sbb-paginator length="100" page-size="20" disabled></sbb-paginator>
Style.

The component has two size, named s and m.

<sbb-paginator length="100" page-size="20" size="s"></sbb-paginator>
Events.

Consumers can listen to the page event on the <sbb-paginator> component to intercept the page change event.
The event contains both the information about the pageIndex and the previousPageIndex,
as well as the length and the pageSize.

Accessibility.

The component has role="group" to semantically group its child controls;
consumers should add an appropriate aria-label attribute with a text
that describes the content controlled by the paginator.

<sbb-paginator aria-label="Select page" length="100" page-size="20"></sbb-paginator>

Angular.

This component is also available for Angular in the package @sbb-esta/lyne-angular.
