Multi-select field cannot be added to the web widget

I can see from previous posts that this issue unfortunately goes way back and that it doesn't seem like there is a solution on the way. That's a shame!

Not being able to add multi-select fields to the web widget has become a huge problem for us. We have had to make a workaround but are not happy with the result at all. 

We needed to include two multi-select fields, with this the form in the web widget would have been user friendly, clean and efficient. Now the result is the complete opposite.
