[EP-tech] Re: "max_items" limit


It has been added to the default 'cfg.d/views.pl':
https://github.com/eprints/eprints/commit/dce1d9c2eca1dcdd89f1906388ba0e45825092ff

- but you're right-  this should get a mention in the docs!

Cheers,
John

Thanks, Gilles.  We should try to add this option to the views documentation

Hi,

You can also change max_items in your cfg.d/views.pl :

         {
                 id => 'year',
                 citation => 'view',
                 menus => [
                         {
                                 fields => [ 'date;res=year' ],
                                 reverse_order => 1,
                                 allow_null => 1,
                         }
                 ],
                 hideup => 1,
*max_items => 3000*,
                 ...

Regards,
GF
