FAQ

Why there are 2 widgets?

Since version 4.0 the widget was migrated to a Gutenberg block. So there will be a Gutenberg block with the most modern code and compatibility and a legacy version that is 100% made in PHP to keep compatibility with older installations.

Why this plugin is not working?

By support experience, like 99% of problems are due to:

• There’s a Javascript error caused by other plugin and it stops any further code execution, check your browser’s logs to find the problem and deactivate the conflict plugin.
• Your template doesn’t have a wp_footer() function, this plugin requires this function to load JS code at the end of the website to improve speed.
• You’re using a plugin that removes WordPress’ JS version and inserts an old one.

How I can send you a translation?

Send me the translated .mo file to migueluseche(a)skatox.com and indicate the language, I can read english or spanish, so please write me on these languages.

Can I use images as bullets or trigger symbols?

Yes, select ‘Empty Space’ as trigger symbol and Save, then you can add any custom background using CSS,
just play with the widget’s classes .jaw_category, .jcl_symbol, .jcl_link.

Can I show this list inside posts?

Yes, only write [jQueryCategoriesList] anywhere inside a post or page’s contest and it will be
replaced for the archive list when rendering the content. You can add the following parameters to change its behavior:

1. showcount ( boolean ): Select if you want to show the count post inside category’s name
2. ‘layout’ ( “right”, “left” ): where to display the symbol
3. ex_sym: the expansion symbol.
4. con_sym: the collapse symbol.
5. effect (“none”, “slide”, “fade”): the JS effect to implement.
6. orderby (“name”,”id”, “count”): how to order categories.
7. orderdir (“ASC”, “DESC”): the direction to order categories.
8. show_empty’ ( boolean ): show categories with no posts.
9. expand (“all”, “none”): expand or collapase all categories.
10. exclude: IDs (comma separated) of the categories to exclude.

How can i add multiples instances?

Since 2.0 you can add as many instances as you want, but there’s another way to do it, just add a new Text widget only with the shortcode [jQueryCategoriesList] then it will have a new copy of the widget.

How I contribute to this plugin?

By using it, recommending it to other users, giving it 5 starts at plugin’s wordpress page, suggesting features or coding new features and finally by DONATING using plugin’s website’s donate link,
with the donation I can spend more time on this project.

Can I have different instances with different configuration?

Since 2.0 it’s possible. Each instance has its own configuration. Shortcode widgets are controlled by shortcode attributes.

Works well with 4.9.8

Chris Dennis October 2, 2018

Haven’t seen any problems running this with WordPress 4.9.8, even though it’s marked as untested for a long time. It must have been well written.

I was look for this widget for a long long period of time!! It works great!

I looked everywhere for a plugin that would do this and I was only satisfied when I got this one. It worked perfectly out of the box and has many configuration options. Really great work!

Nice and Simple

Works really well, especially to create a simple category page listing. Recommended.

Good. Missing a feature.

I like this plugin very much. Easy to use and simple. It’ll be 5 star if the categories are collapsible to show the posts like in “jQuery Archive List Widget”.
