Menu item add multiple cateogry

Hi,

any possible way to add multiple category select in the menu.

Thanks

Please clarify your question in more details

In admin panel , menus => select any one of menu item. The generate submenu have to select category and its generate parent menu → sub menu → children menu.
what if categories has only parent category and it doesn’t have any sub category so sub menu wont generate at all .
In case , if we select multiple category as generate sub menu and it will be mapped that particular menu also if it an multiple category based menu seo path for url can given based input in the menu structure. so process that as path exampe category and category 2 the seo url should be category-and-category2 that path will be showing both category product result .
is this possible to make feature ?
Thanks

Thank you for the clarification. I am afraid, custom development work is required to do it
