I LOVE that when you create a label attribute that there is an option to be able to add a label item if it is not listed. Unfortunately, it does not work in a form though. They can only choose one of the options listed. For this reason, i had to get rid of my label attributes and now they have to type out the information in the form instead of being able to quickly choose a label. I hope this is something that is being worked on!
For us, the crew filling out the forms are often typing on a phone or tablet that doesn’t have a keyboard, so they would much appreciate the labels for the common information that we often repeat a lot instead of having to type it all!
