Multicolumn Category Widget

All styles can be found in css/frontend.css. Since these styles get overwritten when updating the widget, you should add the custom styles to your theme.

Generally the widget supports multiple languages - you can use Loco Translate to add more languages, if needed. If you want to provide a translation in your language which is missing yet, you're welcome to send me the po/mo files for the next update.

The layout uses multiple lists which are displayed next to each other using the CSS rule display:inline-block. This means: If there not enough room to display multiple columns (either because the sidebar of the template is too narrow or the available viewport of the device is very small), the browser will eventually fall back to show only a single column. But this is intentional to make sure that the category list is always completely visible - even on smaller screens or on narrow smaller sidebars - and won't break the layout of the template by using more room as available. In rare cases a template or a plugin changes the default behaviour of the WordPress core function the_widget(), which usually outputs widgets with their own CSS classes - in this case you might have to add your own styles based on the rules in css/frontend.css but without .widget_multicolumncategorywidget. However the better solution would be to check the template and/or other plugins, why the widget specific CSS classes are missing.
