Time hidden submenu

Hey there quangvu89tee,

Hope you’re well today!

You can fix this with some custom CSS by moving your submenu few pixels to the top. If you want to do that please try adding the following CSS code in the style.css file of your child theme or if your theme doesn’t have custom CSS tab add it in your site using the following plugin:

ul.top-menu li ul.sub-menu {
top: 35px;
}

This should fix the issue when moving clicking on sub menu items.

Hope this helps 🙂

Best regards,
Bojan

Glad I could help 🙂

Cheers,
