Today I have seen a very strange issue, where one of my clients said that he has the “List Tools” tab missing from his List.
Unable to see list tools tab from the SharePoint Document Library and List.
Checked the list on other site and it has the List tools tab.
Edited the page list tools tab is available. Stop editing it again disappears.
Checked various option in the List view web part.
Enabled the summary toolbar, full toolbar. It still doesn’t appear on the list menu.
This is the default behavior of the SharePoint 2010, that if we have more than two web parts (especially Content Editor) added on the List view page then ‘List Tools’ menu will not appear.
As a fix, you either need to remove the Content editor web part form the List view page.
As a workaround, I have selected the Full Toolbar option by editing the List Web part. If you click on any section such as New, Action, Settings, you will get ‘List Tools’ option to work with.
If you have any queries/questions regarding the above-mentioned information then please let me know.
I would be more than happy to help you as well as resolves your issues, thank you.
