Open

^{Step-by-step guide}

1. you simply go to the Admin page > Merge duplicate fields  under "Forms"

2. click Merge duplicate fields and if there are any Duplicated fields, It will automatically merge them

Effects of "Merge Duplicate Fields"

The function merges similar/ Duplicated  fields per each form, and it points all the duplicated fields to the first field. 

The function does not delete the duplicated fields from the given Form_Field table in the Database , neither  from the form Layout, but t just points the duplicated Fields to one single Field.

an example below is a duplicated field "NewX" in a form.

1. Before the Duplicated Fields are merged                                                                                                                                                                                                                                                                                    when u search in "Find field Elements" for a field to add to the form, all the Duplicated Fields are returned as different fields.
