It’s an easy way to show and order all posts from category/tag into a page/post. Really handy for showing your tutorials, articles, etcetera. 
It shows as a list(<ul><li>) so it will apply your blog style-sheet as you wish.
Note: If the selected term(category or tag) has a description, it will be shown in a <blockquote> tag.
To see it in action click <a href="http://felipetonello.com/blog/tutoriais-e-artigos/" title="Felipe Tonello blog" rel="nofollow ugc">here</a>.
Usage:
<ol>
<li>
Go to Category Show’s options page and generate the tag.
</li>
<li>
Insert your new tag into your post.
</li>
</ol>
Tags to know:
If you want to apply some CSS, those are the tags you should know: <h3>, <ul>, <li>, <a> and <blockquote>.
Output example:
<pre><code><h3>Category</h3>
<blockquote>Category description, if exists</blockquote>
<ul>
<li><a title="link title" rel="bookmark" href="link">title</a></li>
</ul>
</code></pre>
That’s it!
<h3>TODO</h3>
<ul>
<li>Each topic content preview.</li>
<li>Page support.</li>
<li>A RSS edition of Category Show.</li>
<li>Add widget support.</li>
<li>Select user’s own category in options page. (DONE)</li>
<li>Make it possible to get a date in front of each link.</li>

This plugin excels in giving you full control over the visibility of your a post. By default, any post you add to your WordPress blog will become the topmost post, and will show up immediately on the front page in the first position, and similarly in category/tag/archive pages. Sometimes, you want to create a “low-profile” addition to your blog that doesn’t belong on the front page, or maybe you don’t want it to show up anywhere else in your blog except when you explicitly link to it. This plugin allows you to create such “hidden gems”.
In particular, this plugin allows you to control the visibility of a post in various different views:
<ul>
<li>The Front Page (Homepage, depending on your theme, this may not be relevant)</li>
<li>The Category Page (listing the posts belonging to a category)</li>
<li>The Tag Page (listing the posts tagged with a given tag)</li>
<li>The Authors Page (listing the posts belonging to an author)</li>
<li>The Archive Pages (listing the posts belonging to time period: month, week, day, etc..)</li>
<li>The Search Results</li>
<li>Feeds</li>
</ul>
The posts will disappear from the places you choose them to disappear. Everywhere else they will show up as regular posts. In particular, permalinks of the posts still work, and if you generate a sitemap, with something like the <a href="https://wordpress.org/extend/plugins/google-sitemap-generator/" rel="ugc">Google XML Sitemaps</a> the post will be there as well. This means that the content of your post will be indexed and searchable by search engines.
For a WordPress page, this plugin also allows you to control the visibility with two options:
<ul>
<li>Hide a page on the front page (homepage) only.</li>
<li>Hide a page everywhere in the blog (hiding the page in the search results is optional).</li>
</ul>
This means, technically, whenever pages are listed somewhere using the <code>get_pages</code> filter, this plugin will kick in and either filter it out or not according to the options you choose. The same rules apply regarding permalinks and sitemaps as they do for regular posts.
“WP Hide Post” plugin is a great tool in your arsenal for SEO optimization. It allows you to add plenty of content to your blog, without forcing you to change the nature and presentation of your front page, for example. You can now create content that you otherwise would be reluctant to add to your blog because it would show immediately on the front page, or somewhere else where it would not belong. It’s a must-have feature of WordPress.
Please enjoy this plugin freely, comment and rate it profusely, and send me feedback and any ideas for new features.
