May 2023 Summary

Updates since 1.0.3

New components

Calcite has added new components to enhance and support your UI, which include:

• Navigation and Menu
• Text Area
• Chip Group

Navigation and Menu

Navigation and related components Navigation User and Navigation Logo provide a consistent structure and behavior for users to reliably and consistently navigation your application. Using Navigation with Navigation Logo, and where applicable, Navigation User, can ensure your experiences are consistent and understandable. Navigation can also be useful for containing a Menu and Menu Items.

The Menu and Menu Item components provide a consistent menu structure allowing your users to access and navigate pages, routes, or functionality within your application and experience. They are most often slotted into a Navigation component, but can also be placed in other layout components, such as Shell Panel, Panel, and Flow.

Text Area also supports a specified maximum number of characters with the maxLength property, includes a default (unamed) slot and two footer slots, footer-start and footer-end.

Theming

Calcite includes new workflows to support your UI and brand, which include:

• Focus color and offset variables
• Component sample themes

Focus color and offset variables

Support your workflow using two global CSS variables, also available on individual components, --calcite-ui-focus-color and --calcite-ui-focus-offset-invert. You can alter the focus color from the --calcite-ui-brand color and offset the focus outline inset to 1 (default is 0).

  --calcite-ui-focus-offset-invert: 1;
}
#plane-chip {
  --calcite-ui-focus-color: #C66A4A;
}

Component sample themes

Sample themes are now available for light and dark modes in each sample's "Theming" section, such as List.

Component functionality

Enhancements to support component functionality are now available, which include:

• Color Picker transparency
• List single persist selection
• List change event
• List Items close button
• Tab Title close button
• Modal sticky slots
• Input files support

Color Picker transparency

Color Picker can be configured to include an alpha channel to handle transparency. The alpha channel can be enabled using the alphaChannel property.

<calcite-color-picker alpha-channel></calcite-color-picker>

List single persist selection

List includes a selectionMode of "single-persist", which allows one selected item and prevents de-selection.

    </calcite-list-item>
    <calcite-list-item label="Rivers" description="Large naturally flowing watercourses." value="rivers">
    </calcite-list-item>
</calcite-list>

List change event

List has a calciteListChange event, which listens for selection changes to the component to access the selectedItems property.

const listElem = document.querySelector("calcite-list");

listElem.addEventListener("calciteListChange", () => {

    console.log(selectedItem.value);
  })
});

• Action Group layout inheritance
• Flow Item and Panel action bar

Flow Item and Panel footer

A CSS variable is available to specify the padding of the Flow Item and Panel components with --calcite-flow-item-footer-padding and --calcite-panel-footer-padding. The update deprecates the footer-actions slot for both components; use the footer slot instead.

/* Flow Item footer padding */
calcite-flow-item {
  --calcite-flow-item-footer-padding: 0;
}

/* Panel footer padding */
calcite-panel {
  --calcite-panel-footer-padding: 0;
}

Shell slots

Shell supports alerts, modals, panel-top and panel-bottom slots. Deprecates the center-row slot, use panel-bottom instead.

Resize Shell Panel and CSS variables

Shell Panel's "top" and "bottom" slots now support resizing with the resizable property. There are also CSS variables to support your UI, including:

• --calcite-shell-panel-detached-max-height,
• --calcite-shell-panel-height,
• --calcite-shell-panel-max-height,
• --calcite-shell-panel-max-width,
• --calcite-shell-panel-min-height,
• --calcite-shell-panel-min-width,
• --calcite-shell-panel-width, and
• --calcite-shell-panel-z-index

Shell Panel display mode

Shell Panel now offers a displayMode property, which specifies the component's display in your UI, where:

• "dock" (default): Displays at full height, adjacent to center content.
• "float": Displays without full height and content is seperate and detached from the Action Bar. Content is positioned on top of center content.
• "overlay": Displays at full height, content is positioned on top of center content.

The new offering deprecates the detached and detachedHeightScale properties; use the respective displayMode and heightScale properties instead. Additionally, deprecates the --calcite-shell-panel-detached-max-height CSS variable.

Accessibility

Calcite continues to ensure the applications and experiences you create are usable by a wide range of audiences leveraging the W3C Accessibility Standards. Since January Calcite has added additional accessibility enhancements and resources to support you in developing web applications, which include:

• Conformance report
• Picker functionality and focus trap support
• Avatar assistive technology support

Conformance report

Calcite's conformance report is now available and includes support on the US Access Board (Section 508), Web Content Accessibility Guidelines (WCAG), and current format of the Voluntary Product Accessibility Template (VPAT®).

Picker functionality and focus trap support

Input Date Picker and Input Time Picker support focus trapping and allow toggling the Date Picker and Time Picker component respectivelly when clicking the input or selecting the "Arrow down" key to open, or "Esc" key to close the component dialog.

Avatar assistive technology support

Avatar specifies context to assistive technologies (AT) where the component will be provided additional context to AT with the label property. For non-images, the fullName value will provide context to AT, unless a label value is specified.

1
<calcite-avatar label="A bear" full-name="A bear" thumbnail="https://placebear.com/40/40"></calcite-avatar>

setFocus method

The setFocus() method, which sets focus on the component's first focusable element, is now supported in the Action Group, Date Picker, Dropdown, Pagination, and Split Button components.

1
customElements.whenDefined("calcite-split-button").then(() => document.querySelector("calcite-split-button").setFocus());

Localization

Calcite continues to support localization, meaning the UI content can be adapted to a specific language and culuture. Since January Calcite's localization support includes:

• German - Austria language
• Block handle

German - Austria language

German - Austria (de-AT) is a new Calcite supported language, which includes locale support to the Date Picker component. For instance, January displays as "Jänner" when specifying the locale.

<calcite-date-picker lang="de-at"></calcite-date-picker>

Block handle

Block's movable handle now includes string translations for Calcite's supported languages.
