## FAQ

### The dropdown is closed when click `dropdownRender` area?

See the [dropdownRender example](/components/select/#components-select-demo-custom-dropdown).

### Why is `placeholder` not displayed?

`placeholder` will only be displayed when `value = undefined`, and other values such as null, 0,'', etc. are meaningful values for the JS language.

You can check [JS Language Specification](https://262.ecma-international.org/5.1/#sec-4.3.9) for further details.
