Allow for radio buttons in forms and ways to limit drop down boxes

I’m migrating over from another project management system and one thing that was useful on forms I feel like could be useful in (if it’s not already there and I just don’t know yet). Two ideas here, on the form being able to limit how many selections a user can make on the drop down AND potentially adding the option for a radio button. If only one selection is required then why click a drop down and waste time clicking twice (once for opening the drop down and another for clicking the selection) when you could have a radio button with all the options displayed and the user clicks the one they need to click and there is only 1 click needed. With a large form this saves alot of time.
