Have you ever been frustrated adding more and more categories or tags or any other terms in a rush? Don’t worry anymore. You can add thousands of terms in one go with this plugin.
<h3>How do I do that?</h3>
<ol>
<li>Install the plugin and activate. A new menu called ‘Add Bulk Terms’ will pop up.</li>
<li>Click on the menu and you’ll be taken to a new page where you will see all the registered taxonomy either by theme or any plugin.</li>
<li>First select a taxonomy which you want to add terms.</li>
<li>Then insert the terms in the right side textarea. Make sure each line contains only one term.</li>
<li>Click on ‘Add Now’ button. A little confirmation will pop up just to make sure you have inserted everything correctly. Click yes and BOOM. All terms are added.</li>
</ol>
<h3>What about nesting parent and child?</h3>
This plugin supports to do that. You can go and do nesting. You can indent child levels with a dash (-). For example:
<pre><code>Foo
-Bar
-Baz
</code></pre>
In the example above, ‘foo’ will be parent while ‘bar’ and ‘baz’ will be child of it. 
You can use correct indent to make even more child of child. Example:
<pre><code>Foo
-Bar
--Baz
</code></pre>
Complex nesting example:
<pre><code>Foo
-Child of Foo~~foo-custom-slug
--Grand child of Foo~~grand-child-slug
-Second child of Foo
Baz is sibling of Foo
-Nephew of Foo
--Grand child of Baz
--Second grand child
-Son of Baz
-Daughter of Baz~~daughter-custom-slug
I am a lonely term
Do not have child
</code></pre>
Unfortunately the maximum supported level is as deep as the SEA.
<h3>Features</h3>
<ul>
<li>Unlimited terms per time</li>
<li>Unlimited level of nesting</li>
<li>Supports any registered taxonomy. (only those which can be added or removed within UI)</li>
<li>Uses AJAX request</li>
</ul>
version 2.0 update 
* Custom slugs for each terms. Use the <code>~~</code> symbol to seperate name and slug. 
* Get all terms from selected taxonomy as a template. Later, use that template to add them to another taxonomy. 
* Remove all terms that were added by the plugin from selected taxonomy. (Requires at least WordPress 4.4 and plugin version 2.0 when Adding and deleting the terms)
<h3>Known issues</h3>
<ul>
<li>You can’t add child items to those terms which are already added. If you try to do, the given parent item will add as a new term.</li>
</ul>

<ul>
<li>Replace term archive pages with custom Taxonomy Pages (CPT).</li>
<li>Use the block editor to design archive landing pages.</li>
<li>Includes a Taxonomy Archive Block to display posts.</li>
<li>Fully customizable via templates and filter hooks.</li>
</ul>
<h4>How It Works</h4>
The Taxonomy Page will override the first page of a term archive. In Settings you can choose which taxonomies should have the option to create a Taxonomy Page.
For example, to create a Taxonomy Page for the News category:
<ol>
<li>In Settings → Reading select <code>Category</code>.</li>
<li>Go to Posts → Categories, hover over “News” and click Taxonomy Page.</li>
<li>Edit the Taxonomy Page in the block editor and publish it.</li>
<li>View the page at <code>/category/news</code> (assuming your permalink structure is set to “Post name”).</li>
</ol>
<h4>Taxonomy Archive Block</h4>
When editing a Taxonomy Page in the block editor, you also have access to the Taxonomy Archive Block. This block displays an overview of every post in the term archive. A number of options allow you to alter its behavior:
<ul>
<li>
Number of Posts 
Sets the maximum number of posts displayed in the overview.
</li>
<li>
Toggle Button Text 
Sets the text for the toggle button. This button appears when the total number of posts exceeds the number set in “Number of Posts”.
</li>
<li>
Archive Button Text 
Sets the text for the archive button. This button links to the second page of the term archive. It will be displayed when the amount of posts exceeds <code>Blog pages show at most</code> in Settings → Reading.
</li>
</ul>
<h4>Template Structure</h4>
You can choose a template for the Taxonomy Page in the block editor. Alternatively, you can create your own template, by adding <code>singular-taxonomy-page.php</code> to your theme’s templates, or using the filter hook <code>rich_taxonomy_include_template</code>.
The default template hierarchy, from highest to lowest priority, is as follows:
<ol>
<li><code>singular-taxonomy-page.php</code></li>
<li><code>page.php</code></li>
<li><code>singular.php</code></li>
<li><code>single.php</code></li>
<li><code>index.php</code></li>
</ol>
<h4>Customization</h4>
Template Override: Taxonomy Archive Block
To override the layout of the Taxonomy Archive Block, copy these files into your theme under:
<pre>template-parts/rich-taxonomy/</pre>
Files:
<ul>
<li><code>archive-block-loop.php</code> – Loop of post list</li>
<li><code>archive-block-more.php</code> – Archive button</li>
<li><code>archive-block-toggle.php</code> – Toggle button</li>
<li>
<code>archive-block-wrapper.php</code> – Wrapper of archive
Styles and Scripts
</li>
</ul>
You can override the plugin’s styles and scripts using these hooks:
<ol>
<li><code>rich_taxonomy_block_asset_style</code></li>
<li><code>rich_taxonomy_block_asset_editor_style</code></li>
<li><code>rich_taxonomy_block_asset_script</code></li>
<li><code>rich_taxonomy_block_asset_editor_script</code></li>
</ol>
To change the look & feel, <code>rich_taxonomy_block_asset_style</code> is the best starting point.
Example: Override Style
<pre>// Register style.
add_action( 'init', function() {
 wp_registeR_style( 'my-archive-block', $url, $deps, $version );
} );

// Override handle.
add_filter( 'rich_taxonomy_block_asset_style', function( $handle, $block_name ) {
 if ( 'rich-taxonomy/archive-block' === $block_name ) {
 $handle = 'my-archive-block';
 }
 return $handle;
}, 10, 2 );</pre>
<blockquote>
This style will load on both the front-end and block editor.
</blockquote>
Default Contents
To define the default content of the Taxonomy Page, use the <code>rich_taxonomy_default_post_object</code> filter hook.
Example: Define Default Content
<pre>/**
 * Filter default post object.
 *
 * @param array $args Post object passed to wp_insert_post().
 * @param WP_Term $term Term object assigned to this post.
 * @param string $context Currently only 'api' is supported.
 */ 
add_filter( 'rich_taxonomy_default_post_object', function( $args, $term, $context ) {
 // If specific taxonomy, enter default content.
 if ( 'category' === $term->taxonomy ) {
 // Post body.
 $args['post_content'] = 'Here comes default content.';
 // Publish immediately.
 $args['post_status'] = 'publish';
 }
 return $args;
}, 10, 3 );</pre>
