How can i add options to the SelectPart?

[cellpaddding]

I'm using the forms module and work flow module to save form data.
When i add the select part to my form,i find that i can't add options to the select part.
How can i do it?
Thank you.

I assume we are missing the SELECT and OPTION form elements.

Feel free to create a PR to add these, or even a "Custom" Form element where you could render custom tags.
