WrappedComponent lacks a handleClickOutside(event) function for processing outside click events.

[Robert-Fish]

handleClickOutside = () => {
  console.log('hello world');
  };

export default connect(
  null,
  { toggleProject }
)(onClickOutside(ProjectDropdown));

I keep getting this error whenever i click on or near the component. "Uncaught Error: WrappedComponent lacks a handleClickOutside(event) function for processing outside click events."

It looks like you tried to define a click handler in global scope, and that's not going to work.

As per the installation section in the README.md: either declare the handler as a normal function that's part of your ProjectDropdown class (first two examples), or make sure you have an options object with 'handleClickOutside' property and pass that into the wrapping function as second argument (third example).
