Sharepoint Library Tool Menu Missing in Document Library
The Tool Menu gets hidden when there are web parts added to a document library page. I will show you how to get rid of the webparts on the page so the Tool Menu will reappear.
This applies to SharePoint 2010 and 2013. The example below is from SharePoint 2010.
1. Navigate to the document library that is missing the tool menu.
2. Click on Site Actions, Edit Page.
3. Delete the unwanted webpart/s by navigating to the far right of the webpart and clicking the arrow seen below. Click on delete, click Yes to the permanently delete the web part box.
4. Click on Stop Editing and the library tools will be back.
