Display the variables from the data frame



Hello Group,

I am trying to develop an application where the user can upload the file using the file input and then I want to display the variables in the form of checkbox from the data frame.


I referred the above link. I would like to have something similar , but , i want to render the column names in the checkbox group.

The whole idea is to, display the column names in the checkbox and later the user could modify the datatype of the column.

Sample of code supporting this would be helpful.
