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

<p>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。</p>
