This function solves the problem (这个功能解决的问题)

Hope dropdown has a small arrow just like Popover, as a "Props"

Expected API (期望的 API)

and the documentation of "dropdown" has no description about "placement"

[Talljack]

dropdown support popover props, maybe you can take a look at the popover documentation.

poppover props has "showArrow" props but it does not work because it does not handle the situation when internalRenderBody has value with "showArrow" props in PopOverBoby.
