We\'ve installed \'bootstrap-tagsinput.js\' and the \'typeahead\' plugin for doing a tyepahead drop down for tags for an input field in one of our forms. The hardcoded tags work
I'd like to clarify some of the other answers since they're not saying it clearly enough.
Currently, the highest voted package for typeahead on Atmosphere is by sergeyt:typeahead. Apparently, there's some issues when using this package.
After fiddling with it for about an hour, I searched for an alternative. After installing mrt:bootstrap3-typeahead - everything worked as expected.
So my recommendation is to try that package if you're having problems.
