Problem: jquery autocomplete does not show a list of suggestions on click
Note: Please do not mix up jquery.ui autocomplete with jquery.autocomplete plugin.
Here is a solution that may help:
$("#inputfield").autocomplete(val,{ selectFirst: true, autoFill:true, minChars:0, cacheLength:1, matchContains: true, mustMatch: true, }).bind('focus', function(){ $(this).click(); });
