Walkthrough

This update introduces formatting changes to the LESS stylesheet for the select-dropdown component, standardizing spacing and removing unused CSS. Additionally, it restructures the HTML markup for the "select all" option in the Vue select component, wrapping the icon and label into separate containers with specific classes. No logic or exported entities are altered.

Poem

In the garden of code, a dropdown blooms anew,
With icons in spans and labels in view.
The stylesheet is tidy, the markup refined,
Like carrots in rows, all neatly aligned.
A hop and a skip, the changes are done—
Select all with style, and bugs there are none! 🥕✨

packages/vue/src/select/src/pc.vue (2)

The filtered variant now uses the same DOM structure as the primary option, eliminating inconsistent alignment.

packages/theme-saas/src/select-dropdown/index.less (5)

9-9: Introduce item prefix class variable
Defining @select-dropdown__item-prefix-cls centralizes the BEM prefix for dropdown items and supports the updated DOM structure.

Targeting the recycle-scroller wrapper and item prefix resets margin-right to zero, aligning items under the new structure.

---

47-51: Remove bottom margin on slot items
Clearing the default margin-bottom ensures uniform spacing for slot-based items in the dropdown.

---

92-95: Adjust icon vertical alignment
Tweaking the top margin on .tiny-svg elements corrects icon alignment within the option rows.
