Dashboard / Form Results view width in 5.5
PermalinkIn yoursite/concrete/single_pages/dashboard/reports/forms.php
after line 20 where jQuery starts, add following (or preferably make an copy of the file to /yoursite/single_pages/dashboard/reports/ to override the core file and make the changes there):
if($(".zebra-striped").width() > 900) { $(".span16").width($(".zebra-striped").width()+40); }
That makes the surrounding div to strech nicely according to the width of the results table and it looks a bit better than the table exploding out the dialog. The method is far from bullet-proof, as it calls the elements by classname because there are no id's. It still works well, as there's only one element of each class in the single page.
I hope to see a "real" and more universal fix to the problem, as the too wide views make the new UI look pretty bad in situations like this.

What version of C5 are you using? Also, did you make sure you inserted the code correctly after the line jQuery(function($) { ...
Thanks for posting this solution.
