javascript - typeahead dropdown results align right - pull-right - Stack Overflow

Trying to understand how to implement the pull-right class within the angular typeahead dropdown only.

Issues:

• input is located on RHS of window (which is typical for a search input box)
• my results are wider then my input (and the containing div)
• I need right side of dropdown to align with right side of input box, and to extend on the left past (below) the input width.
• (dropdown only needs shifting, text alignment within doesn't change and should stay aligned to left. ie. Not an RTL as in this issue: RTL for angularjs bootstrap's typeahead)

Applying pull-right class to a containing div doesn't seem to affect the drop-down independently of the input.
I'm not sure where else to put it ?

Is there a CSS method of controlling the alignment of the dropdown div?

Have modified the documentation example in the following Plunker:

• includes the pull-right class in the containing div
• placed in a containing div to narrow the width (perhaps unnecessary ?)

If you type 'ang' into the plunker example inputbox you'll see the results spill past the right of the window.

  <div class='column'>
    <div class='container-fluid pull-right' ng-controller="TypeaheadCtrl">
      <h4>Asynchronous results</h4>
      <pre>Model: {{asyncSelected | json}}</pre>
      <input type="text" ng-model="asyncSelected" placeholder="Locations loaded via $http" typeahead="address for address in getLocation($viewValue)" typeahead-loading="loadingLocations" class="form-control">
      <i ng-show="loadingLocations" class="glyphicon glyphicon-refresh"></i>
    </div>
  </div>

I've looked at the following issues, which don't seem to help me:

• SO issue 22075432 - typeahead-alignment-issue
• github bootstrap issues 2045

You would need to override the inline-style that get generated for .drop-down-menu by typeahead. Something along the the lines of:

<script>
  $('#myInput').on('keypup', function() {
    $(".dropdown-menu").css({ "left": "auto", "right": "10px" });
  });
</script>

Plunker

Note: set right to whatever the distance is between your input and the RHS of the page/window

---

Update

For a non-jQuery version you would have to override the left css attribute of .dropdown-menu using !important

.dropdown-menu{
  left: auto !important;
  right:10px;
}

Updated Plunker

Another option is use the typeahead-popup-template-url hook with a little change on the default template implementation.

Using this approach you can use more than one instance of ui-typeahead defining the desired layout one by one.

Don't forget to tune the right length for your specific usage.

(function () {
	'use strict';

  angular.module('myAnswer', ['ui.bootstrap']);
  
})();

<html ng-app="myAnswer">
  <head>
    <script src="//ajax.googleapis./ajax/libs/angularjs/1.6.1/angular.js"></script>
    <script src="//ajax.googleapis./ajax/libs/angularjs/1.6.1/angular-animate.js"></script>
    <script src="//ajax.googleapis./ajax/libs/angularjs/1.6.1/angular-sanitize.js"></script>
    <script src="//angular-ui.github.io/bootstrap/ui-bootstrap-tpls-2.5.0.js"></script>
    <script src="example.js"></script>
    <link href="//netdna.bootstrapcdn./bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
  </head>
  <body>
  <div class='container-fluid'>

    <h4>Static arrays</h4>
    <pre>Model: {{selected | json}}</pre>
    
<script type="text/ng-template" id="typeahead-popup-right.html">
  <ul class="dropdown-menu" ng-show="isOpen() && !moveInProgress" ng-style="{top: position().top+'px',left: 'auto', right: '15px'}" role="listbox" aria-hidden="{{!isOpen()}}">
    <li class="uib-typeahead-match" ng-repeat="match in matches track by $index" ng-class="{active: isActive($index) }" ng-mouseenter="selectActive($index)" ng-click="selectMatch($index, $event)" role="option" id="{{::match.id}}">
      <div uib-typeahead-match index="$index" match="match" query="query" template-url="templateUrl"></div>
    </li>
  </ul>
</script>    
    
    
    <input type="text" ng-model="selected" uib-typeahead="state for state in ['Espirito Santo', 'Minhas Gerais', 'Rio de Janeiro', 'São Paulo'] | filter:$viewValue" class="form-control" typeahead-popup-template-url="typeahead-popup-right.html">
    <small class="help-block">Try typing 'Rio' or 'Janeiro'</small>
  </div>
  </body>
</html>
