Version

3.4.4

Environment

macOS Sierra 10.12.6, Chrome 65

Reproduction link

Steps to reproduce

Open your console and find that trigger container with ant-dropdown-trigger class. It may have another class my-custom-dropdown.

What is expected?

className my-custom-dropdown should pass into trigger container span as a prop, intuitively.

What is actually happening?

className lost in trigger container somehow.

@afc163 Indeed, we have a component Groups. It works like:

<Groups className="container" childClassName="item">
    <Link>item1</Link>
    <Button>item2</Button>
    <Dropdown>{item3}</Dropdown>
</Groups>

The Groups will pass item as className for each child.
I just wanna to pass className into the container of Dropdown.
However, Dropdown ignore className.
IMO, this is not an intuitive behavior. It will confuse developers.
Shall we fix this problem?

You can create a PR to rc-trigger for this.
