Display new tab when add new item to checklist

[Julie_Nguyen0]

Hi,

Recently we have old SharePoint 2010 migrated to SharePoint Online.  Of the 3 checklist items we have, only 1 would open in a new tab when we click to add new item to checklist.  The other 2 checklists would open in a modular tab on the side.  How can I change it so it would open in a new tab when we click to add new item in the checklist.  Please help.

Thank you,

Julie N

Hi Julie

Are you you using the modern or classic view?

If classic, you can go to list settings -> Advanced -> Launch forms in dialogue to yes ->

If modern, this should open on the right side of the page.

Hope that helps

Hello NotAlex,

I don't know if it's modern or classic view.  Is there a way to check?

The list settings on all checklists are the same (yes is selected).  I'm very puzzling why only 1 checklist open in a new tab while the other 2 open on the right side of the page when add new item in checklist.

Thank you for all your help.

Julie N.
