Oddthinking

If your blog is over a year or two old, you may have noticed the list of archive pages is getting unwieldy.
This plugin is a widget that compresses the size of the arcgives list to two lines per year (three if the lines are narrow) rather than one line per per month.

WordPress doesn’t support date archives for custom post types out of the box. This plugin adds the rewrite rules needed to view the date archives at a <a href="https://wordpress.org/support/article/introduction-to-blogging/#pretty-permalinks" rel="ugc">pretty permalink</a>.
Example permalink (url) for a custom post type <code>events</code> date archive.
<pre><code>https://example.com/events/2015/06/12
</code></pre>
The calendar, archive and recent posts widget are similar to the existing WordPress widgets, but with extra (custom post type) options added.
The cpt date archives use the same theme template files as the normal WordPress date archives. Extra <a href="https://github.com/keesiemeijer/custom-post-type-date-archives/wiki/Theme-Template-Files" rel="nofollow ugc">template files</a> and <a href="https://github.com/keesiemeijer/custom-post-type-date-archives/wiki/Functions" rel="nofollow ugc">template functions</a> are available for use in the custom post type date archives.
