Summary

Added a wrappingType property to the Breadcrumbs component that controls how text is displayed when there is not enough space. The property defaults to "None" which truncates text with ellipsis, but can be set to "Normal" to allow text wrapping.

Problem

When using breadcrumbs with very long labels, the text would wrap to multiple lines, making the breadcrumb navigation look inconsistent and taking up unnecessary vertical space. Users requested a way to control this behavior and force truncation with ellipsis for a cleaner, single-line appearance.

Original issue showing multiline breadcrumb text

Solution

The implementation adds a new wrappingType property that:

  • Defaults to "None" - truncates text with ellipsis keeping items on one line
  • Can be set to "Normal" - allows text to wrap to multiple lines when needed
  • Applies to both link items and the current location label for consistency
  • Uses the existing WrappingType enum following UI5 WebComponents patterns

API Usage

<!-- Default behavior: truncate long text -->
<ui5-breadcrumbs>
  <ui5-breadcrumbs-item href="#">Home</ui5-breadcrumbs-item>
  <ui5-breadcrumbs-item href="#">VeryLongItemName</ui5-breadcrumbs-item>
  <ui5-breadcrumbs-item>CurrentLocation</ui5-breadcrumbs-item>
</ui5-breadcrumbs>

<!-- Allow text to wrap to multiple lines -->
<ui5-breadcrumbs wrapping-type="Normal">
  <ui5-breadcrumbs-item href="#">Home</ui5-breadcrumbs-item>
  <ui5-breadcrumbs-item href="#">VeryLongItemName</ui5-breadcrumbs-item>
  <ui5-breadcrumbs-item>CurrentLocation</ui5-breadcrumbs-item>
</ui5-breadcrumbs>

Implementation Details

  • Added wrappingType: ${WrappingType} = "None" property to Breadcrumbs.ts
  • Updated BreadcrumbsTemplate.tsx to pass wrappingType to both Link and Label components
  • Added comprehensive test cases to verify functionality
  • Maintains backward compatibility - default behavior unchanged
  • Follows existing UI5 WebComponents patterns using standard WrappingType enum

Fixes #12219.
