haha, I have an idea,
I can use this component to achieve a bilingual website,
I can creat some chinese categories and some english categories,
and ues this component as the main navigation,
the title link include in the translate locales file en.yml and zh_CN.yml
the homepage and categories page i can use a translated theme component( even it’s a static page, ) achieve.
and hide the default category-drop,
and in my think, it is good for me just use two language in our website.
