If the field type is Choice and the Display choices values is set to Checkboxes and also the Allow fill in is Yes then qListForm displays the field in the same way as SP OOB ListForm does and allows "Own values".
When using qListForm, for the SharePoint choice field there is an option to “Specify your own value.” However, it doesn’t provide the same option for the ‘Radio Button’ option. Is this by design or a missing configuration?
