What does data-cfapps-unplaceable mean?


With some websites the design of the application is corrupted and the behavior is unexpected. I noticed that when the happens all the tags are marked with data-cfapps-unplaceable. BTW, I am appending directly to the body tag so the user does not have to pick a location Here is an example:

<div class="popup" data-cfapps-unplaceable=""><div class="exit_popup box" data-cfapps-unplaceable="">

I suspect this is the reason the elements are not showing correctly. Any idea what is the cause and how to fix it?


Hi, since the site is corrupt or having unexpected behavior, we use this tag to make sure that we don’t add elements which could farther break the site.


I see.

  • Is there a way to check the site in the preview mode and let the owner know his site is corrupt?

  • Can you give some examples of corrupt side or unexpected behaviors?

  • What’s weird is the my elements are added to the site, but they are just all over the place in such a case? how can that be if the elements are not added?


Here are some examples of different sites with this error:



It depends on the site and how your app is adding these elements. I recommend running that site through an HTML validation check like: https://validator.w3.org/nu/
