<h4>About</h4>
With this lightweight plugin you can create a knowledge base that contains your categories and posts.
To display your knowledge base you can use a block, a shortcode or a widget.
You can customize your knowledge base with attributes.
It’s also possible to display categories and posts from a custom post type (such as WooCommerce product categories and products).
With this plugin you can also create a FAQ or wiki in the same way as a knowledge base.
<h4>How to use</h4>
After installation add the VS Knowledge Base block or the shortcode <code>[knowledgebase]</code> to a page to display your knowledge base.
Or go to Appearance > Widgets and use the VS Knowledge Base widget.
Default settings categories:
<ul>
<li>4 columns when using block or shortode</li>
<li>1 column when using widget</li>
<li>Order by name</li>
<li>Ascending order (A-Z)</li>
<li>Empty categories are hidden</li>
<li>Parent and subcategories are displayed separately</li>
</ul>
Default settings posts:
<ul>
<li>Order by date</li>
<li>Descending order (new to old)</li>
<li>All posts are displayed</li>
</ul>
You can customize your knowledge base with attributes.
<h4>Attributes</h4>
You can customize your knowledge base by adding attributes to the block, the shortcode or the widget.
<ul>
<li>Add custom CSS class to knowledge base: <code>class="your-class-name"</code></li>
<li>Change the number of columns: <code>columns="3"</code></li>
<li>Disable the columns: <code>columns="0"</code></li>
<li>Include certain categories: <code>include="1,3,5"</code></li>
<li>Exclude certain categories: <code>exclude="8,10,12"</code></li>
<li>Display empty categories too: <code>hide_empty="0"</code></li>
<li>Display category description: <code>category_description="true"</code></li>
<li>Change the number of posts per category: <code>posts_per_category="5"</code></li>
<li>Reverse the order of posts: <code>order="ASC"</code></li>
<li>Display posts by title: <code>orderby="title"</code></li>
<li>Display posts in random order: <code>orderby="rand"</code></li>
<li>Display post counter: <code>post_count="true"</code></li>
<li>Display post meta (date and author): <code>post_meta="true"</code></li>
<li>Display View All link: <code>view_all_link="true"</code></li>
<li>Change label of View All link: <code>view_all_link_label="your label"</code></li>
<li>Change label of post without title: <code>no_post_title_label="your label"</code></li>
<li>Change the “no categories are found” text: <code>no_categories_text="your text"</code></li>
</ul>
Example: <code>[knowledgebase include="1,3,5" hide_empty="0" post_meta="true"]</code>
When using the block or the widget, don’t add the main shortcode tag or the brackets.
Example: <code>include="1,3,5" hide_empty="0" post_meta="true"</code>
With the columns attribute you can set the number of columns between 1 and 4.
The knowledge base becomes 2 columns in small screens (except when number of columns is set to 1).
You can also disable the columns. This can be handy if you only want to use your own styling.
The columns attribute will be ignored when using the block or widget. Because you can set the columns via the block or widget settings.
<h4>Post tags</h4>
Besides displaying posts by category you can also display posts by tag: <code>taxonomy="post_tag"</code>
<h4>Custom post types</h4>
It’s also possible to display categories and posts from a custom post type (such as WooCommerce product categories and products).
To display these categories and posts you should add 2 attributes: “taxonomy” and “post_type”
WooCommerce:
<ul>
<li>Product categories and products: <code>taxonomy="product_cat" post_type="product"</code></li>
<li>Include product category image: <code>taxonomy="product_cat" post_type="product" woo_image="true"</code></li>
<li>Display by tag instead of category: <code>taxonomy="product_tag" post_type="product"</code></li>
</ul>

Yada Wiki provides a wiki post type, custom tags and categories, an index, and a table of contents option. The plugin allows you to link your wiki pages together using the wiki page titles.
Note: As of Yada Wiki 3.6, for current users who have been manually adding HTML tags or special characters to their shortcodes, for security reasons these must be filtered on save. An exception was added for the EM tag because I saw support tickets where users said they were using this tag. If you have been manually editing the shortcodes then you may want to test before installing version 3.6.
There are two easy to use shortcode buttons available on the editor toolbar. Rather than try to remember the shortcodes and their values, it is recommended that you use these buttons to generate the shortcodes for you.
The “Add Wiki Link” Button: 
When you click the first button, the add wiki link button, a pop-up opens where you enter the title of the wiki page you are linking to in the “Link” text box. You can optionally enter text into the “Show” text box that you want to show for the link, or leave that blank to just show the title. There is the ability to manually add an “anchor” parameter for on-page links. Please see the documentation for more information on this.
When you click “OK”, a shortcode is inserted into your edit window at the cursor location. For example to link to a wiki page called “How To Make Iced Coffee” but show the text for the link as “How To Make My Favorite Drink”:
[yadawiki link=”How To Make Iced Coffee” show=”How To Make My Favorite Drink”]
You use Wiki Link shortcodes to create the structure of linked pages.
The “Add Wiki Listing” Button: 
The Add Wiki Listing button gives you three options for adding some collected output.
Output TOC Page 
The first option inserts a shortcode that will output your “TOC” page. With Yada Wiki, you can create a special wiki page with the title of “TOC” that will serve as the table of contents for your wiki. You can use wiki links and style the table of contents as you like in the post editor. Selecting this option allows you to embed the TOC page in another page. For example:
[yadawikitoc show_toc=”true”]
Output Wiki Category 
The second option inserts a list of the wiki pages for one of your wiki categories. You can optionally choose to output the list by title or by creation date. For example:
[yadawikitoc show_toc=”true” category=”Drinks” order=”title”]
Output Index 
The third option inserts a grid of your wiki pages or categories. The output is in a responsive table-like grid and you can choose the number of columns. For example, to output wiki pages:
[yadawiki-index type=”pages” columns=”4″]
An example for listing a single wiki category by title:
[yadawiki-index type=”category-name” category=”States” columns=”3″]
An example for listing all wiki categories by title:
[yadawiki-index type=”all-categories-name” columns=”3″] 
Note that in the index listing the category hierarchy only goes down one level deep from to the top.
Sidebar Widgets: 
There are two Yada Wiki widgets. One for showing the TOC page and a list of article titles for a given category in the sidebar and the other for showing recent wiki articles. Please see the FAQ section for information about using the sidebar widgets.
