This plugin can be used to fetch a list of all posts from specific category using shortcode [postslist].
Here is an example of this:
[postlist cat=”cat1,cat2″ tags=”tag1,tag2,tag3″ requesttype=”1″]
[postlist cat="cat1,cat2" tags="tag1,tag2,tag3" requesttype="1"]
where
cat : category slug not category name
tages : tag slug not tag name
requesttype : 1 (all of the tags should be present)
0 (any of the tag should be present)
number : the number of posts you want show (use -1 to show all posts)
