How to disable menu when membership plans are open

Hello, Tuan,

Cannot figure out how to disable menus of the website when a page with a membership plan is open - to create a sort of a sales page without distractions.

Will be grateful for any suggestion.

Disable menus ? What menus you are talking about ? Maybe send me the link to the page so that I can think about it

However, I am afraid of with the way Joomla designed to work (Joomla core), I don't think we can have a solution for this problem
