Thanks for the PR, will make a minor release later in the week.

Note: I think passing the selected attribute will only work for uncontrolled components.

For controlled components, simply setting the value of the select should add selected to the correct option elements for you (value should be an array for a multiple select).

Note: while it's now possible to add selected to option elements, it isn't encouraged. React will issue this warning:

Warning: Use the `defaultValue` or `value` props on <select> instead of setting `selected` on <option>.
