This is an example of using Tether Drop with React Portal (and Redux for managing the state). I was asked if using React Portal is redundant, as both libraries pull the content into the
<body>. Using only Drop would cause an invariant violation in React becuase of the DOM mutation, so I'm using React Portal to first bring it outside without React complaining (I don't know how React Portal does it, I haven't checked out the source, but it works). Once it's out of React's supervision, I can apply Drop to it.
Dropdown.jsxis the actual dropdown component
App.jsxis just an demo that uses it
This is my lazy way out of this limitation using an existing library that has much more features than you need, but chances are that you're going to need a library like React Portal anyway for stuff like modals.
