Multicolumn Category List on Sub Menu

Hello everyone,

Thank you for this amazing plugin. I have problem and could not solve it. I want to show my categories in multiple columns on sub menu named Categories. So I created a menu item “Categories”, clicked to mega menu settings and there is a option “select a widget to add to panel”, I selected Multicolumn Category widget (https://www.ads-software.com/plugins/multicolumn-category-widget/). But It doesn’t work, It still shows in 1 column like original category widget. Is there a any way can i make it done? Thank you.
