typeahead keyboard navigation not working

[egore]

Using typeahead the keyboard navigation is not working. This can be seen at https://morgul.github.io/ui-bootstrap4/.

To fix the issue we need to change in uib/template/typeahead/typeahead-popup.html
The line:
<li class=\"uib-typeahead-match\" ng-repeat=\"match in matches track by $index\"
to:
<li class=\"uib-typeahead-match dropdown-item\" ng-repeat=\"match in matches track by $index\"

As a hack in 3.0.6 this can be set in the uncompressed jsfile before minification.

Tested in multiple browsers on Windows & Mac/iPhone.

I personally set typeahead-focus-first="false" at the input field as a default, I find the auto-select a bit too intrusive for the user. That's just an input.

Nice hack, I was unable to figure it out due to time constraints.

Thanks for finding this. While the solution provided above does fix the issue with keyboard navigation, it doesn't use correct markup for Bootstrap 4 dropdowns, which causes dual padding, and dual highlights on hover.

I combined the typeahead-match template with typeahead-popup.html, and then replaced the typeahead-popup template in the $templateCache in a run-block:

import { ITemplateCacheService } from 'angular'

const typeaheadPopup = `<div
  class="dropdown-menu"
  ng-show="isOpen() && !moveInProgress"
  ng-style="{top: position().top+'px', left: position().left+'px'}"
  role="listbox"
  aria-hidden="{{!isOpen()}}"
  >
  <a
    class="uib-typeahead-match dropdown-item clickable"
    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}}"
    ng-bind-html="match.label | uibTypeaheadHighlight:query"
    ng-attr-title="{{match.label}}"
  ></a>
</div>`

uibTemplateFix.$inject = ['$templateCache']
export function uibTemplateFix($templateCache: ITemplateCacheService) {
  $templateCache.put(
    'uib/template/typeahead/typeahead-popup.html',
    typeaheadPopup,
  )
}

import { uibTemplateFix } from './configs/uib-template-fix.config'
angular.module('myApp', [ 'ui.bootstrap' ]).run(uibTemplateFix)
