Ah - in the List Settings
> Advanced Settings
section, there is a section for List Experience
with choices for Default
,New Experience
or Classic Experience
.
Classic Experience makes it look somewhat like SP 2010 with the Ribbon - it brings back the Ribbon!
If you change this to Class Experience then you will have the option for Edit Page
for the List.
The javascript command to enter Page Layout Mode is simply this: ChangeLayoutMode(false);
but it doesn't work in the "New Experience" mode. It only works if you set the list to Classic mode.
Now, after you change the list to Classic Mode
you will no longer see List Settings
in the gear-button dropdown. You'll have to click in the list to pop open the ribbon and use the List Settings button in the Ribbon. The whole experience is not very consistent.
However, there is one more caveat that I've found. If you switch to Classic Experience
and add a webpart (such as a Content Editor) you cannot switch back to New Experience
as long as there are extra webparts on the page. Even if you change the setting again in List Settings
> Advanced Settings
- it just won't change back; the setting will stay set the way you mark it, but the display won't change. I guess New Experience
is not capable of displaying other webparts.
One more thing to add: Say you do want it back to New Experience
- and say you go and delete those extra webparts. Even if you left the setting set to New Experience
you still have to go and change it again to make it take effect now that you've removed the webparts.
Enjoy!
