Project dropdown list in horizon is truncated unexpectedly

[Garrett Hayes]

When assigning 15+ projects to a single user, the Horizon dropdown menu that allows quick project selection unexpectedly truncates the list.

When using this dropdown menu with 15+ projects, the menu is not scrollable and not all projects are visible and selectable.

Verified in Openstack Mitaka on Ubuntu 14.04.

Hi Garret,

I couldn't reproduce the bug. I did this:
- I created 15 projects and assigned to an user
- Clicked on the dropdown to change my project.
- I was able to see more than 15 projects.

Make sure you don't have a custom maximum number of items to display in a dropdown in this variable: https://github.com/openstack/horizon/blob/master/openstack_dashboard/local/local_settings.py.example#L404-L405

I set the variable to 10 and saw only 10 projects: http://pasteboard.co/efkX4cOWR.png

Tested on 9.1.0

Didn't see this in the documentation anywhere - you are correct about this setting. Please mark as invalid.

Hello,
On Ocata openstack, created 50 Projects & assigned it to user but on the Horizon dashboard the dropdown lists only 30 Projects, which is default value in /etc/openstack-dashboard/local_settings.py. Changed the value of
# Specify a maximum number of items to display in a dropdown.
DROPDOWN_MAX_ITEMS = 55

to 55 and restarted apache and memcached services. still the dropdown is only reflecting only 30 items.
Can someone help..
