Hello i am using typeahead script in my we project and it working fine but when i use the same js files in mobile then i got the error "element.typeahead is not a function ". i have checked that all the js files are loaded properly on the browser. i am using typeahead with angularjs. same js files are working on web view but not working on mobile. is there any other typeahead js library for mobile ? Thanks in advance.
