Thank you for your response but that didn't work out as I want to hide the tab based on user role in the left nav bar and the code for that tab is in the source code under the skin folder. first I have created the page on DNN and added page name to the hyperlink in the source code Also, I have tried to disable the option to display that tab in the menu on DNN page settings but that didn't work as that tab source code is in under the skin folder and Below is the theme created for the left nav bar menu. I am not sure how/what to update on the source code file skin/theme file. Please let me know if you have any idea regarding what to update in the source code file. FYI, I am aware that how to display the page content on DNN based on user role but I don't know how to hide/show the particular left-nav tab itself based on the user role. Please find below the source code:
