Angular UI bootstrap - show dropdown on typeahead-no-results
提问by Thomas
tryng to get a dropdown when no result on typeahead but, the drop down menu dosen't show view
尝试在输入前没有结果时获得下拉菜单，但下拉菜单不显示视图
<div class="dropdown">
<div class="form-group">
<input placeholder="V?lg kunde" type="text" ng-model="customer" typeahead-editable="false" uib-typeahead="customer as customer.customer for customer in customers | filter:$viewValue | limitTo:8" class="form-control"
typeahead-popup-template-url="customPopupTemplate.html"
typeahead-min-length="0"
typeahead-no-results="noResults">
</div>
<div ng-if="noResults" dropdown-toggle>
<ul class="dropdown-menu" >
<li><a href="#">No result</a></li>
</ul>
</div>
</div>
removing class="dropdown-menu" gives me the li with no result, but i dont get it as a dropdown menu
删除 class="dropdown-menu" 给了我没有结果的 li，但我没有把它作为下拉菜单
who do i toggle this dropdown menu on no result ?
如果没有结果，我该给谁切换这个下拉菜单？

The problem is that the dropdown never is triggered, and by that not rendered properly. You are just making the markup visible.
问题是下拉菜单永远不会被触发，并且没有正确呈现。您只是使标记可见。
You can set auto-close="disabled"and is-open="true"to show the dropdown properly upon noResults:
您可以设置auto-close="disabled"并is-open="true"正确显示下拉列表noResults：
<div class="form-group">
<input placeholder="V?lg kunde" type="text" ng-model="customer" typeahead-editable="false" uib-typeahead="state for state in states | filter:$viewValue | limitTo:8" class="form-control" typeahead-min-length="0" typeahead-no-results="noResults">
<span ng-if="noResults" auto-close="disabled" is-open="true" uib-dropdown uib-dropdown-toggle>
<ul class="uib-dropdown-menu" >
<li><a href>no results</a></li>
</ul>
</span>
</div>

NB: The plnkr is using ui-bootstrap version 0.14.3, if you are using a version prior to 0.14.0 then do not append uib-prefixes.
注意：plnkr 使用 ui-bootstrap 版本 0.14.3，如果您使用的是 0.14.0 之前的版本，则不要附加uib-前缀。
