Select: Add triggerProps or className for styling the trigger button

[natalyjazzviolin]

Feature Request

Problem

Currently, there's no way to apply custom styles to the Select trigger button for responsive designs. The component doesn't expose className, triggerProps, or any props that forward to StyledSelectTrigger.

Use Case

We need to adjust the Select button's padding, font-size, and height for mobile breakpoints in our responsive
layouts.

Proposed Solution

Add one of:

1. triggerProps that forwards to StyledSelectTrigger
2. className prop that applies to the trigger button
3. triggerClassName specifically for the button

This has been resolved by PR #837 (merged Feb 18, 2026), which added triggerProps to the Select component, allowing consumers to pass custom props (including className and inline styles) directly to the trigger button. Closing this issue.
