Hi Anthony,
I accomplished this via model - Thanks! for pointing. Below is the
sample logic
*All written In Model*
> global user_right1
> user_right1=False # Default value provided
>
code written to retrieve actual values and set the user_right1=<value>
In layout.html (whatever name of the layout be) I passed this variable
> {{if user_right1 ==True:}}
> Show the HTML stub
> {{pass}}
>
Done
Thanks,
*Rahul *
