The `DMultiSelect` component provides a customizable multi-select
dropdown with support for both mouse and keyboard interactions.
### Parameters
#### `@loadFn` (required)
An async function that returns the data to populate the dropdown
options.
```javascript
const loadFn = async () => {
return [
{ id: 1, name: "Option 1" },
{ id: 2, name: "Option 2" },
];
};
```
#### `@compareFn`
A function used to determine equality between items. This is
particularly useful when working with complex objects. By default, `id`
will be used.
```javascript
const compareFn = (a, b) => {
return a.name === b.name;
};
```
#### `@selection`
An array of pre-selected items that will be displayed as selected when
the component renders.
```javascript
const selection = [
{ id: 1, name: "Option 1" },
{ id: 2, name: "Option 2" },
];
```
#### `@label`
Text label displayed in the trigger element when no items are selected.
```javascript
@label="Select options"
```
### Named Blocks
#### :selection
Block for customizing how selected items appear in the trigger.
```javascript
<:selection as |result|>{{result.name}}</:selection>
```
#### :result
Block for customizing how items appear in the dropdown list.
```javascript
<:result as |result|>{{result.name}}</:result>
```
#### :result
Block for customizing how errors appear in the component.
```javascript
<:error as |error|>{{error}}</:error>
```
### Example Usage
```javascript
<DMultiSelect
@loadFn={{this.loadOptions}}
@selection={{this.selectedItems}}
@compareFn={{this.compareItems}}
@label="Select options">
<:selection as |result|>{{result.name}}</:selection>
<:result as |result|>{{result.name}}</:result>
<:error as |error|>{{error}}</:error>
</DMultiSelect>
```

This update adds a ✨ _new_ `<PostList />` component, along with it's child components (`<PostListItem/>` and `<PostListItemDetails />`). This new generic component can be used to show a list of posts.
It can be used like so:
```js
/**
* A component that renders a list of posts
*
* @component PostList
*
* @args {Array<Object>} posts - The array of post objects to display
* @args {Function} fetchMorePosts - A function that fetches more posts. Must return a Promise that resolves to an array of new posts.
* @args {String} emptyText (optional) - Custom text to display when there are no posts
* @args {String|Array} additionalItemClasses (optional) - Additional classes to add to each post list item
* @args {String} titleAriaLabel (optional) - Custom Aria label for the post title
*
*/
```
```hbs
<PostList
@posts={{this.posts}}
@fetchMorePosts={{this.loadMorePosts}}
@emptyText={{i18n "custom_identifier.empty"}}
@additionalItemClasses="custom-class"
/>
```
