This plugin enables you to create unlimited custom sidebar/widget areas and switch existing areas. You can do this without touching your theme.
This plugin utilizes term meta api and so it works only with WordPress 4.4 and above.
Your theme needs to use <code>is_active_sidebar()</code> when calling <code>dynamic_sidebar()</code> function.
This will work.
<pre><code>if ( is_active_sidebar( 'sidebar-1' ) ) {
 dynamic_sidebar( 'sidebar-1' );
}
</code></pre>
This doesn’t work.
<pre><code>dynamic_sidebar( 'sidebar-1' );
</code></pre>
If you only want to output your custom sidebar, put this code on where you want to display the sidebar in your theme.
<pre><code>do_action( 'dynamically_dynamic_sidebar' );
</code></pre>

ウィジェットエリアをいくつでも定義し、カテゴリやタグ、カスタム分類ごとに差し替えたり、投稿・ページ・カスタム投稿から使いたいサイドバーを指定したりすることができます。「スクリーンショット」のタブをごらんいただくと、イメージが湧きやすいと思います。
