Is it so hard to solve?

Can anyone of the development team look at this one, please?

For information : the fix is to remove the input on column :).
I don't think we get a good way to do it in a clean way for core (working with javascript …)

If it does not work as expected by the users and the error is unsolvable at the moment, shouldn't there be some warning when constructing this question?

No need a warning if we don't show the input box :). No input box => “no issue” ;)

OK

Please update to the latest version.

Still in 3.5.4 git .

And sincerely : i dislike new javascript way to do things, seeme more complex than needed

Same problem as I reported in 13441 - lasting since LS 2.06+ 151215, the oldest version I'm working width ;)
@DenisChenu: the plugin may help in some cases, but often I'd like to hide not empty columns

@orvil : yes, BUT : i put the js because the issue for hidding columns are the way to hide it on same page.

Do a system to hidding it via PHP seems OK, but hidding it in JS make a buggy javascript. If you have a way to show/hide column only with one class update on one element id : OK.

@DenisChenu: I got your point for same page function. But why buggy js? I've used a solution like this in jquery:
https://jsfiddle.net/ovillani/zb8Laamw/2/
Needs (additional) class for evey col/cell but works fine

A great about the jsfiddle. But need update in Expression Manager.

Expression Manager use id, then need a javascript function to move id to class/name or better : data-javaId for example

PS : It's OK if we allow to have col width to sum up to 100% :)

@dominikvitt . That's one.

Please update to the latest version.

Gah

added to the backlog. Fix only for master branch (LS5)

We already started with this. Delayed though
