Multicolumn Category Widget

Этот виджет позволит вам вывести рубрики в несколько столбцов.

After installation, just add the widget to desired sidebar or footer and optionally enter a custom title and the number of columns to be displayed.

By default two columns are used, but you can set any number of columns you like in the backend.
