# Collapsible Component

 Collapsible components allow users to expand and collapse sections of content. Built with a hidden checkbox pattern,
 collapsibles work without any JavaScript and support animated transitions via CSS grid.

| collapsible-content  | Modifier | Animated content area revealed when open             |
| collapsible-arrow    | Modifier | Adds a rotating arrow indicator to the title         |
| collapsible-group    | Modifier | Wrapper for accordion-style grouped collapsibles     |
| collapsible-overlay  | Modifier | Overlay variant for drawer-style collapsibles        |
| collapsible-peek     | Modifier | Shows a glimpse of content when collapsed            |

| is-collapsible-close | Modifier | JS-applied class to force closed state               |

## Basic Usage

A hidden checkbox drives the open/close state. The `label` triggers it; the `collapsible-content` div animates open.

## With Arrow Indicator

Add `collapsible-arrow` to the label to get a rotating chevron that reflects open/close state.

```html
<div class="collapsible border border-base-soft rounded-lg">
  <input type="checkbox" class="collapsible-toggle" id="col-arrow" />
  <label for="col-arrow" class="collapsible-title collapsible-arrow px-4 py-3 font-medium">What is Frutjam?</label>
  <div class="collapsible-content">
    <div>
      <div class="px-4 pb-3 text-sm opacity-70">
        Frutjam is a Tailwind CSS v4 component library built with CSS utilities and a PostCSS plugin.
      </div>
    </div>
  </div>
</div>
```


## Multiple Collapsibles

```html
<div class="flex flex-col gap-2">
  <div class="collapsible border border-base-soft rounded-lg">
    <input type="checkbox" class="collapsible-toggle" id="col-1" />
    <label for="col-1" class="collapsible-title collapsible-arrow px-4 py-3 font-medium">Section One</label>
    <div class="collapsible-content">
      <div>
        <div class="px-4 pb-3 text-sm opacity-70">Content for the first section.</div>
      </div>
    </div>
  </div>

  <div class="collapsible border border-base-soft rounded-lg">
    <input type="checkbox" class="collapsible-toggle" id="col-2" />
    <label for="col-2" class="collapsible-title collapsible-arrow px-4 py-3 font-medium">Section Two</label>
    <div class="collapsible-content">
      <div>
        <div class="px-4 pb-3 text-sm opacity-70">Content for the second section.</div>
      </div>
    </div>
  </div>

  <div class="collapsible border border-base-soft rounded-lg">
    <input type="checkbox" class="collapsible-toggle" id="col-3" />
    <label for="col-3" class="collapsible-title collapsible-arrow px-4 py-3 font-medium">Section Three</label>
    <div class="collapsible-content">
      <div>
        <div class="px-4 pb-3 text-sm opacity-70">Content for the third section.</div>
      </div>
    </div>
  </div>
</div>
```


## Open by Default

Add `checked` to the checkbox input to start the panel open.

```html
<div class="collapsible border border-base-soft rounded-lg">
  <input type="checkbox" class="collapsible-toggle" id="col-open" checked />
  <label for="col-open" class="collapsible-title collapsible-arrow px-4 py-3 font-medium">Open by default</label>
  <div class="collapsible-content">
    <div>
      <div class="px-4 pb-3 text-sm opacity-70">
        This content is visible on initial load.
      </div>
    </div>
  </div>
</div>
```


## JS Controlled

Toggle `collapsible-open` on the wrapper element instead of using a checkbox — useful when the trigger lives elsewhere.

```html
<div class="collapsible collapsible-open border border-base-soft rounded-lg" id="js-col">
  <button
    class="collapsible-title collapsible-arrow px-4 py-3 font-medium"
    onclick="this.closest('.collapsible').classList.toggle('collapsible-open')"
  >
    Toggle via JS (starts open)
  </button>
  <div class="collapsible-content">
    <div>
      <div class="px-4 py-3 text-sm opacity-70 border-t border-base-soft">
        No hidden checkbox needed — state is managed by the <code>collapsible-open</code> class.
      </div>
    </div>
  </div>
</div>
```


## Peek Variant

`collapsible-peek` shows a clipped preview with a gradient fade and an overlay trigger.
 Override `--peek-height` to control how much content is visible when collapsed.

```html
<div class="collapsible collapsible-peek rounded-xl border border-base-soft" style="--peek-height: 5rem;">
  <input type="checkbox" class="collapsible-toggle" id="col-peek" />
  <div class="collapsible-content">
    <div class="p-4 text-sm leading-relaxed">
      <p>Frutjam is a Tailwind CSS v4 component library built around a PostCSS plugin architecture. Every component is a set of <code>@utility</code> definitions that integrate natively with Tailwind's utility pipeline.</p>
      <p class="mt-3">Theming is handled entirely through CSS custom properties. Swap themes by setting a <code>data-theme</code> attribute on any container, or override individual tokens inline.</p>
      <p class="mt-3">Components ship with sensible defaults and are designed to compose cleanly.</p>
    </div>
  </div>
  <label for="col-peek" class="collapsible-overlay">
    <span class="btn btn-sm">Read more</span>
  </label>
</div>
```


## JS & React Helper

Use `createCollapsible` from `frutjam/js` or `useCollapsible` from `frutjam/react` for programmatic control and automatic `aria-expanded` sync on any trigger.

## External Trigger with collapsible-group

Wrap a trigger and a collapsible in `collapsible-group` to let labels outside `.collapsible` respond to its open/close state via `is-collapsible-open` and `is-collapsible-close`.

```html
<div class="collapsible-group border border-base-soft rounded-lg p-4 flex flex-col gap-3">
  <div class="flex items-center justify-between">
    <span class="font-medium">Section A</span>
    <label for="cg-1" class="btn btn-sm btn-ghost">
      <span class="is-collapsible-close">Expand</span>
      <span class="is-collapsible-open">Collapse</span>
    </label>
  </div>
  <div class="collapsible">
    <input type="checkbox" class="collapsible-toggle" id="cg-1" />
    <div class="collapsible-content">
      <div>
        <div class="text-sm opacity-70">
          This content is toggled by the button above, which lives outside <code>.collapsible</code> but inside <code>.collapsible-group</code>.
        </div>
      </div>
    </div>
  </div>
</div>
```
