Author: Fernando Briano List Category Posts is a simple WordPress plugin which allows you to list posts from a category into a post/page using the [catlist] shortcode. This shortcode accepts a category name or id, the order in which you want the posts to display, and the number of posts to display. You can use [catlist] as many times as needed with different arguments. Great to use WordPress as a CMS, and create pages with several categories posts. Usage: [catlist argument1=value1 argument2=value2]
Installation:
Upload listcat directory into you wp-content/plugins/ directory. Login to your WordPress Admin menu, go to Plugins, and activate it. Edit the default.php file on templates to customize the way the categories are displayed, or use the default one included in the plugins code. You can use several different templates if you want. You can find the List Category Posts widget in your widgets. Hasnt been tested, still in development, but usable. If youre updating List Category Posts from version 0.1, you must change the code in the pages using it, since its not backwards compatible. LCP now uses WordPresss shortcode API, in order to allow arguments. You should chang the previous [catlist=ID] to [catlist id=ID].

Can I use it inside others HTML tag, such a table? Yes you can. In version 0.3.1 was fixed a limitation that made impossible to do such a thing. So always use the latest version. Can I use it more than one time per post? Yes. Anytime you want. But remember that Category Show doesnt have page support yet, it will be in its next versions. How do I know my category slug? You need to see at your Categories Options on Wordpress Admin. But probably is the category or tag name without special characters, such as #@!?�?�. Remember that you dont need to remove the white spaces. If my category has any special character? Just remove the special character by the same character without accent. If your category name is like "Olá tudo bom?" use it like %%wpcs-ola tudo bom%%

faq:
How do I get multiple widgets? Wordpress 2.3 - 2.7 Below your available widgets section, you should see a section asking "How many Folding Category widgets would you like?". Simply change the number in the box and click save. For some reason it does not always add extra widgets on the first attempt, but it works fine the second time. Wordpress 2.8+ Simply drag the focal icon to your sidebar(s) as needed. I sorted the list by X, its not working You need to Rebuild the Cache for changes to take effect. I upgraded but receive various php errors Data structures have changed to increase performance and may be incompatible with the latest version. Please Rebuild the Cache to resolve the errors. You need only do it once. The navigation is not updated / showing old data Ensure that "Automatically rebuild cache" is enabled or you manually click "Build Cache". = I get a Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 274388 bytes) = In some rare cases Wordpress is unable to update its internal cache object and crashes out. Please see http://wordpress.org/support/topic/161173?replies=3 for progress on this issue.
