Onsen UI: https://onsen.io/2/
Patternfly: https://www.patternfly.org/ , https://github.com/patternfly/patternfly/blob/master/QUICKSTART.md
I tried to find addons for OnsenUI and Patternfly but could not.
Right now I use bower to install them and I shared about it here OnsenUI with emberjs · Issue #1 · frandiox/OnsenUI-Material-Tabbar · GitHub.
In the same fashion patternfly works with emberjs.
I would like community members to pitch in to create these two addons for the benefit of all.
