I am not sure if you were able to sort them in the past (just tested it in 2.73 and 2.50). Looks more like a feature request.

@DenisChenu, do you know more?

It's a feature request :).

Previously (2.6lts) : we load WHOLE survey and use jqgrid , then we can sort by anything. BUT : if you more than 150 survey it take a lot of time for loading.

Here : we need to create false attributes in https://github.com/LimeSurvey/LimeSurvey/blob/7f14f95efcdac03b59d6fdf705905afbcfcf7dfa/application/models/Survey.php#L1525 it can be done, but it's more a new feature iin my opinon.

PS : another feature is have a filter to each column , and can have dropdown for some (Group/Owner/Anonymized).

@cdorin, we should actually name it a regression because at previous LS versions like 2.6.7 LTS that was doable.

2.6.7lts with more than 300 survey‘s survey list i unusuable.
3.X with more than 2000 survey's still usauble without issue.

Not really a regression

As Denis underlined, this will not work with big instances where there are lots of surveys in the survey list. I also talked to Carsten and it seems not feasible (at least not at the moment)

It's feasible, see https://github.com/LimeSurvey/LimeSurvey/commit/3337b5ae3efee04a5153485c610aeea997985698 for a sample

But : this need lot of work since is adding «false» attribute and create new setter/getter
And Survey::search need to be completely reworked before … to use cleaner Yii way.

Will bring the topic again after the new devs join :)

@cdorin: Time to pick a new developer and let him/her have a look :-)
