I am using Angular JS - ui.bootstrap.typeahead:
I would like to click a button and focus an input field and automatically show the typeahead suggestion dropdown. I have a directive that automatically focuses the input field when the button is clicked. How can I show the dropdown automatically so the user can use the down arrow, or click, to quickly choose a user?
I have created a Plunker with the ui-bootstrap JS file editable for tinkering:

This is my full script:
<!doctype html>
<html ng-app="plunker">
<head>
<link href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet">
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.2/angular.js"></script>
<script src="ui-bootstrap-tpls-0.10.0.js"></script>
</head>
<body>
<script>
angular.module('plunker', ['ui.bootstrap'])
.directive('focusMe', function($timeout, $parse) {
return {
//scope: true, // optionally create a child scope
link: function(scope, element, attrs) {
var model = $parse(attrs.focusMe);
scope.$watch(model, function(value) {
if(value === true) {
$timeout(function() {
element[0].focus();
});
}
});
}
};
});
function TypeaheadCtrl($scope, $http) {
$scope.selected = undefined;
$scope.states = ['Alabama', 'Alaska', 'Arizona', 'Arkansas', 'California', 'Colorado', 'Connecticut', 'Delaware', 'Florida', 'Georgia', 'Hawaii', 'Idaho', 'Illinois', 'Indiana', 'Iowa', 'Kansas', 'Kentucky', 'Louisiana', 'Maine', 'Maryland', 'Massachusetts', 'Michigan', 'Minnesota', 'Mississippi', 'Missouri', 'Montana', 'Nebraska', 'Nevada', 'New Hampshire', 'New Jersey', 'New Mexico', 'New York', 'North Dakota', 'North Carolina', 'Ohio', 'Oklahoma', 'Oregon', 'Pennsylvania', 'Rhode Island', 'South Carolina', 'South Dakota', 'Tennessee', 'Texas', 'Utah', 'Vermont', 'Virginia', 'Washington', 'West Virginia', 'Wisconsin', 'Wyoming'];
$scope.opened = false;
$scope.open = function() {
$scope.opened = true;
}
$scope.close = function() {
$scope.opened = false;
}
}
</script>
<div class='container-fluid' ng-controller="TypeaheadCtrl">
<h4>How can I open the typeahead dropdown automatically when button is pressed?</h4>
<p>I have a directive that automatically focuses on the field but I can't seem to automatically show the typeahead. Even adding down arrow key click support would be great.
<br/><br/>
<button class="btn btn-default" ng-show="!opened" ng-click="open()">Open Input and show typeahead!</button>
<button class="btn btn-default" ng-show="opened" ng-click="close()">Close Input</button>
<br/><br/>
<input type="text"
focus-me="opened"
ng-show="opened"
ng-model="selected"
typeahead="state for state in states | filter:$viewValue | limitTo:8"
class="form-control">
<br/>
<pre ng-show="opened">Model: {{selected | json}}</pre>
</div>
