0.4.0

This release updates Ignite UI for Blazor to the latest igniteui-webcomponents@7.4.1 release with highlights noted below:

Added

New Components

• IgbBreadcrumbs and IgbBreadcrumb - A navigation trail. IgbBreadcrumbs has the list role and Separator sets the icon between the items (tree_expand when not set); put it in a <nav aria-label="..."> element, as the ARIA breadcrumb pattern requires. Each IgbBreadcrumb takes its content, usually an anchor, in the default slot, with prefix / suffix slots around it and a separator slot that replaces the icon of that item. Current sets aria-current="page", and Disabled sets aria-disabled and removes the slotted content from the tab sequence. #1881

Combo, Color Picker, Date Picker, Date Range Picker, Tooltip

• New ScrollStrategy property, already available on Dropdown and Select. It sets what the popup does when a container scrolls: PopoverScrollStrategy.Hide (default) hides it while its anchor is fully out of view, Scroll keeps it visible and anchored, Close closes the component, including a Sticky tooltip. The date pickers ignore it in Dialog mode. #2355

Button Group

• The single selection modes now use the radio group keyboard pattern: the group is one tab stop, and the arrow keys move the focus and the selection together, skipping disabled buttons and wrapping at both ends. Alignment selects the keys - ArrowLeft / ArrowRight following the text direction, or ArrowUp / ArrowDown - and sets the aria-orientation of the group. Multiple mode is unchanged. #2385

Changed

• Combo, Color Picker, Date Picker, Date Range Picker, Dropdown, Select, Tooltip: the popup now hides while its anchor is fully scrolled out of view, as ScrollStrategy defaults to Hide. Before, it stayed visible. Set ScrollStrategy="PopoverScrollStrategy.Scroll" to keep the previous behavior. #2355
• Dropdown, Select, Tooltip: the popup no longer moves along the viewport edge to stay in view; it only flips to the opposite side.
• Popups: positioned with native CSS anchor positioning in browsers that support it (Chrome/Edge 133+, Firefox 147+, Safari 26+). Other browsers use @floating-ui/dom as before, now loaded only when needed.
• Button Group: the radiogroup / group role and the disabled state are now on the igc-button-group element itself, so an aria-label or aria-labelledby set on IgbButtonGroup names the group.

Fixed

For the complete list of fixes arriving with the updated web components, see the 7.4.0 and 7.4.1 release notes - highlights include a <label> bound through for or wrapping the component now naming Checkbox, Switch, Radio, Rating and Slider (a click on it toggles or focuses the control), an aria-label / aria-labelledby set on a form component now naming its native editor, the Combo Label no longer replaced by its selection status text as the accessible name, a Combo or Select that opened and immediately closed again on a click of its label, a single click event (none when disabled) from a click on the label of Input, Date Time Input, Date Range Picker, File Input, Mask Input and Textarea, a Date Picker Label set after the first render reaching the native input in dropdown mode, and the documented container (Date Picker) and ranges (Date Range Picker) CSS parts now being exported.

Breaking Changes

• PopoverScrollStrategy: Block is replaced by Hide. The web component no longer supports blocking the scroll while a popup is open; replace PopoverScrollStrategy.Block with Hide, Scroll or Close.
