<p>The default Recent Posts widget is exceptionally basic. I always find myself in need of a way to easily display a selection of posts from any combination post type or taxonomy. Hence, Flexible Posts Widget.</p>
<p>Flexible Posts Widget (FPW) is more than just a simple alternative to the default Recent Posts widget.  With many per-instance options it is highly customizable and allows advanced users to display the resulting posts virtually any way imaginable.</p>
<h4>Features & options</h4>
<ul>
<li>Customizable widget title</li>
<li>Get posts by post type(s) and/or taxonomy & term(s) or directly by a list of post IDs.</li>
<li>Control the number of posts displayed and the number of posts to offset.</li>
<li>Option to display the post feature image.</li>
<li>Select the post feature image size to display from existing image sizes: thumbnail, medium, large, post-thumbnail or any size defined by the current theme.</li>
<li>Order posts by: date, modified date, ID, title, menu order, random, Post ID Order; and sort posts: ascending or descending.</li>
<li>Each widget’s output can be customized by user-defined templates added to the current theme folder.</li>
<li>Multi Language support. Compatible with <a href="http://wpml.org/" rel="nofollow ugc">WPML</a> and <a href="https://wordpress.org/plugins/polylang/" rel="ugc">PolyLang</a> for sure. Not tested with other multi-language plugins, but it should work.</li>
</ul>
