I have installed the new odoo 8 beta, both from the nightly DEB's on ubuntu 15.04, as on windows 10 with the windows EXE.
I remember that odoo 8 had several free bootswatch templates installed from which you can choose in the web builder (spacelab, amelia, cerullian, etc). I can not find that option either. There is no choice of free themes offered.
BUT I digged into odoo9, and I see that the files for these free bootswatch themes are installed:
/usr/lib/python2.7/dist-packages/openerp/addons/theme_bootswatch/static/src/less/amelia
/usr/lib/python2.7/dist-packages/openerp/addons/theme_bootswatch/static/src/less/cerulean
/usr/lib/python2.7/dist-packages/openerp/addons/theme_bootswatch/static/src/less/cosmo
/usr/lib/python2.7/dist-packages/openerp/addons/theme_bootswatch/static/src/less/cyborg
/usr/lib/python2.7/dist-packages/openerp/addons/theme_bootswatch/static/src/less/flatly
/usr/lib/python2.7/dist-packages/openerp/addons/theme_bootswatch/static/src/less/journal
/usr/lib/python2.7/dist-packages/openerp/addons/theme_bootswatch/static/src/less/readable
/usr/lib/python2.7/dist-packages/openerp/addons/theme_bootswatch/static/src/less/simplex
/usr/lib/python2.7/dist-packages/openerp/addons/theme_bootswatch/static/src/less/slate
/usr/lib/python2.7/dist-packages/openerp/addons/theme_bootswatch/static/src/less/spacelab
/usr/lib/python2.7/dist-packages/openerp/addons/theme_bootswatch/static/src/less/united
How can I enable these themes?
