List Category Posts allows you to list posts by category in 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, the number of posts to display and many more parameters. You can use [catlist] as many times as needed with different arguments. Usage: [catlist argument1=value1 argument2=value2].

Real stuff:

1

[catlist id=1 numberposts=5 pagination=yes instance=1]

2

[catlist id=10 numberposts=15 pagination=yes instance=2]
