+
+# Sort Plugin
+
+Alpine's Sort plugin allows you to easily re-order elements by dragging them with your mouse.
+
+This functionality is useful for things like Kanban boards, to-do lists, sortable table columns, etc.
+
+The drag functionality used in this plugin is provided by the [SortableJS](https://github.com/SortableJS/Sortable) project.
+
+<a name="installation"></a>
+## Installation
+
+You can use this plugin by either including it from a `<script>` tag or installing it via NPM:
+
+### Via CDN
+
+You can include the CDN build of this plugin as a `<script>` tag; just make sure to include it BEFORE Alpine's core JS file.
+
+```alpine
+<!-- Alpine Plugins -->
+<script defer src="https://cdn.jsdelivr.net/npm/@alpinejs/sort@3.x.x/dist/cdn.min.js"></script>
+
+<!-- Alpine Core -->
+<script defer src="https://cdn.jsdelivr.net/npm/alpinejs@3.x.x/dist/cdn.min.js"></script>
+```
+
+### Via NPM
+
+You can install Anchor from NPM for use inside your bundle like so:
+
+```shell
+npm install @alpinejs/sort
+```
+
+Then initialize it from your bundle:
+
+```js
+import Alpine from 'alpinejs'
+import sort from '@alpinejs/sort'
+
+Alpine.plugin(sort)
+
+...
+```
+
+<a name="basic-usage"></a>
+## Basic usage
+
+The primary API for using this plugin is the `x-sort` directive. By adding `x-sort` to an element, its children become sortable—meaning you can drag them around with your mouse, and they will change positions.
+
+```alpine
+<ul x-sort>
+    <li>foo</li>
+    <li>bar</li>
+    <li>baz</li>
+</ul>
+```
+
+<!-- START_VERBATIM -->
+<div x-data>
+    <ul x-sort>
+        <li>foo</li>
+        <li>bar</li>
+        <li>baz</li>
+    </ul>
+</div>
+<!-- END_VERBATIM -->
+
+<a name="sort-handlers"></a>
+## Sort handlers
+
+You can react to sorting changes by passing a handler function to `x-sort` and adding keys to each item using `x-sort:key`. Here is an example of a simple handler function that shows an alert dialog with the changed item's key and its new position:
+
+```alpine
+<div x-data="{ handle(key, position) { alert(key + ' - ' + position)} }">
+    <ul x-sort="handle">
+        <li x-sort:key="1">foo</li>
+        <li x-sort:key="2">bar</li>
+        <li x-sort:key="3">baz</li>
+    </ul>
+</div>
+```
+
+<!-- START_VERBATIM -->
+<div x-data="{ handle(key, position) { alert(key + ' - ' + position)} }">
+    <ul x-sort="handle">
+        <li x-sort:key="1">foo</li>
+        <li x-sort:key="2">bar</li>
+        <li x-sort:key="3">baz</li>
+    </ul>
+</div>
+<!-- END_VERBATIM -->
+
+As you can see, the `key` and `position` parameters are passed into the handler function on every sorting change. The `key` parameter is the value provided to `x-sort:key`, and the `position` parameter is its new position in the list of children (starting at index `0`).
+
+Handler functions are often used to persist the new order of items in the database so that the sorting order of a list is preserved between page refreshes.
+
+<a name="sorting-groups"></a>
+## Sorting groups
+
+This plugin allows you to drag items from one `x-sort` sortable list into another one by adding a matching `.group` modifier to both lists:
+
+```alpine
+<div>
+    <ul x-sort.group.todos>
+        <li x-sort:key="1">foo</li>
+        <li x-sort:key="2">bar</li>
+        <li x-sort:key="3">baz</li>
+    </ul>
+
+    <ol x-sort.group.todos>
+        <li x-sort:key="1">foo</li>
+        <li x-sort:key="2">bar</li>
+        <li x-sort:key="3">baz</li>
+    </ol>
+</div>
+```
+
+Because both sortable lists above use the same group name (`todos`), you can drag items from one list onto another.
+
+> When using sort handlers like `x-sort="handle"` and dragging an item from one group to another, only the destination lists handler will be called with the key and new position.
+
+<a name="drag-handles"></a>
+## Drag handles
+
+By default, each child element of `x-sort` is draggable by clicking and dragging anywhere within it. However, you may want to designate a smaller, more specific element as the "drag handle" so that the rest of the element can be interacted with like normal, and only the handle will respond to mouse dragging:
+
+```alpine
+<ul x-sort>
+    <li>
+        <span x-sort:handle> - </span>foo
+    </li>
+
+    <li>
+        <span x-sort:handle> - </span>bar
+    </li>
+
+    <li>
+        <span x-sort:handle> - </span>baz
+    </li>
+</ul>
+```
+
+<!-- START_VERBATIM -->
+<div x-data>
+    <ul x-sort>
+        <li>
+            <span x-sort:handle> - </span>foo
+        </li>
+        <li>
+            <span x-sort:handle> - </span>bar
+        </li>
+        <li>
+            <span x-sort:handle> - </span>baz
+        </li>
+    </ul>
+</div>
+<!-- END_VERBATIM -->
+
+As you can see in the above example, the hyphen "-" is draggable, but the item text ("foo") is not.
+
+<a name="ghost-elements"></a>
+## Ghost elements
+
+When a user drags an item, the element will follow their mouse to appear as though they are physically dragging the element.
+
+By default, a "hole" (empty space) will be left in the original element's place during the drag.
+
+If you would like to show a "ghost" of the original element in its place instead of an empty space, you can add the `.ghost` modifier to `x-sort`:
+
+```alpine
+<ul x-sort.ghost>
+    <li>foo</li>
+    <li>bar</li>
+    <li>baz</li>
+</ul>
+```
+
+<!-- START_VERBATIM -->
+<div x-data>
+    <ul x-sort.ghost>
+        <li>foo</li>
+        <li>bar</li>
+        <li>baz</li>
+    </ul>
+</div>
+<!-- END_VERBATIM -->
+
+<a name="ghost-styling"></a>
+### Styling the ghost element
+
+By default, the "ghost" element has a `.sortable-ghost` CSS class attached to it while the original element is being dragged.
+
+This makes it easy to add any custom styling you would like:
+
+```alpine
+<style>
+.sortable-ghost {
+    opacity: .5 !important;
+}
+</style>
+
+<ul x-sort.ghost>
+    <li>foo</li>
+    <li>bar</li>
+    <li>baz</li>
+</ul>
+```
+
+<!-- START_VERBATIM -->
+<div x-data>
+    <ul x-sort.ghost x-sort:config="{ ghostClass: 'opacity-50' }">
+        <li>foo</li>
+        <li>bar</li>
+        <li>baz</li>
+    </ul>
+</div>
+<!-- END_VERBATIM -->
+
+<a name="custom-configuration"></a>
+## Custom configuration
+
+Alpine chooses sensible defaults for configuring [SortableJS](https://github.com/SortableJS/Sortable?tab=readme-ov-file#options) under the hood. However, you can add or override any of these options yourself using `x-sort:config`:
+
+```alpine
+<ul x-sort x-sort:config="{ filter: '.no-drag' }">
+    <li>foo</li>
+    <li class="no-drag">bar (not dragable)</li>
+    <li>baz</li>
+</ul>
+```
+
+<!-- START_VERBATIM -->
+<div x-data>
+    <ul x-sort x-sort:config="{ filter: '.no-drag' }">
+        <li>foo</li>
+        <li class="no-drag">bar (not dragable)</li>
+        <li>baz</li>
+    </ul>
+</div>
+<!-- END_VERBATIM -->
