## Where to use it

Every catalogue needs one. Picture an online wine shop where buyers sort by price, rating or newest arrivals, then flip the arrow to see the cheapest or the priciest bottles first. Splitting “what” from “which direction” keeps the list of options short. If you're searching for a sort by dropdown for an e-commerce page, this covers it.

Label the current choice clearly, like “Price” with the arrow beside it, so people remember how the list is ordered. Put it right above the product grid, next to the result count, where eyes already are.

## Prompt for AI assistants

Paste this into ChatGPT, Claude, Cursor, v0 or Lovable to adapt the block to your stack (Tailwind, Vue, Svelte…):

````text
I want to add the “Sort menu with direction arrow” block (Filters) from AIMRAN Library to my project.

## What it is
Choose what to sort by, then tap the arrow to flip between ascending and descending.

## Chosen settings
- Main color: #0071e3
- Secondary color: #8ec5ff
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)

## What I need
1. Add it to my project with the same look and animation as the reference code: same sizes, colours, radii, shadows, timings and easing.
2. It is built with plain HTML and CSS (the reference wraps it in a React component with its CSS). If my project uses something else (Vue, Svelte, Astro, plain HTML…), translate it without losing any behaviour. If I use Tailwind, turn the styles into classes; if not, keep the CSS in its own file.
3. Expose the settings above as props (or CSS variables) with those values as defaults.
4. Make it work well on phones: nothing that depends only on hover, touch targets of at least 44 px and no overflow on 320 px screens.
5. Make it look right in light and dark mode.
6. Keep it accessible: semantic HTML, roles and aria-* where needed, visible focus and keyboard support.
7. Respect prefers-reduced-motion: with reduced motion, no big animations but the same end result.
