In the recent project, I was trying to utilize the Current Navigation itself for our Navigation Purpose. For that, we have come up with a Script to Create and make the Current navigation through PowerShell script here.
But after doing all those things, the Navigation is not visible on the Left Hand side. After doing some analysis, found an interesting tip. Thought of sharing to the community.
1. Go to Site Settings.
2. Under Look and Feel, Click Tree View
3. Select the Check Box – Enable Quick Launch
4. Click OK.
Then, the quick launch will be visible on the Site.
