This Inline editing ,how to.No. Lists are "read only", unless you use the inline edit plugin, although if this is to do with your other questions about hiding rows, I don't think that would help.

I can't find where is it.Ihave Fabrik 3.0.9.
Thanks for your support! I Give up.I'll try upgrade on new Joomla and Fabrik ; however Thanks a lot.Probably in the downloads section, or you can update from github, and do a "Discover".
However, I think inline edit in 3.0.9 is somewhat flaky.
Any particular reason you are on 3.0.9? It's unsupported, written for an end-of-lifed and unsupported version of J!.
