I am working in a lifter LMS it work like charm. I have set a button inside the lesson page. I want to customize that, it will only shown after completion of a lesson or anybody mark that lesson as complete.
Please see the screenshot for more clarity (http://prntscr.com/hjptpk)
Please help me. I am stuck in the middle. Any help will be appreciated.
There is no easy way to do that. Perhaps you can create a new lesson at the end of each section, and this lesson is only accessible if the prior lesson is complete. This lesson will contain whatever content you want.
