Drop down
When dragging the drop-down menu into the navigation bar, please note that it must be dragged into the "menu", otherwise it may not be able to shrink on other devices.
As shown in the picture below, drag the "drop-down menu" into the "menu", and the green cursor only needs to be in the yellow area.
After dragging it in, you can check whether the "footprint" below shows "dropdown" in the "menu".
How to set a link: Select the corresponding menu, click the "Upward" icon, and select "Hyperlink".
On the right side, you can set the linked page, page anchor, URL, email, and phone number.
