# Navbar that tucks links into More

> When space runs out, the last links move into a More menu with a counter; drag the handle or change the width to watch.

## Where to use it

The priority plus pattern for responsive menus: links stay in the bar while they fit, and the ones that do not move into a More dropdown with a counter that bumps on every change. A resize observer recalculates on any width, so it works in sidebars, cards and real headers. The current page is marked in both places, and the dropdown works with arrows and Escape.

Use the width slider or drag the handle to test it, and set the main and secondary colors for the active link. Order the links by importance, since the last ones are the first to move.

I want to add the “Navbar that tucks links into More” block (Navigation) from AIMRAN Library to my project.

## What it is
When space runs out, the last links move into a More menu with a counter; drag the handle or change the width to watch.

## Chosen settings
- Main color: #0f766e
- Secondary color: #ccfbf1
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Width: 24em (from 12 to 30em)
- Text: "Norte"

## 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.
