| Requires at least: 2.7 | ||
| Tested up to: 3.4.1 | ||

||
| This widget will let you display a list of the most recent posts in a single category in your sidebar. | ||
|
|
||
| == Description == | ||
|
|
||
| Sure, WordPress has a widget for displaying your most recent posts, but what if you want to only display the posts from a single category in a widget, and not everything? This plugin Widget lets you set the title, category, and quantity of posts to display, then it kicks out a list of the most recent posts in that category. | ||
|
|
||
| == Installation == | ||
|
|
||
| 1. Upload the file `widget_cat_posts.php` to the `/wp-content/plugins/` directory | ||
| 1. Activate the plugin through the 'Plugins' menu in WordPress | ||
| 1. Position the widget in the desired sidebar through the `widgets` admin page | ||
| 1. Set the category and number of posts to display | ||
|
|
||
| == Frequently Asked Questions == | ||

|
|

| * Now Multi-Widget Friendly, with 200% more awesome! | ||
|

|
||
| == Upgrade Notice == | ||
