File
                File Input is a field which the user can use to upload one or more files (photos, documents or any other
                file type) from local storage.
              
            Basic example
The file input is the most gnarly of the bunch and requires additional JavaScript if you’d like to hook them up with functional Choose file… and selected file name text.
                            
                              
                            
                          
                        Add the disabled attribute to the <input> and the custom
                markup will be updated to appear disabled.
