v1.2.0-beta1 – Custom and Remote Filtering

New Features

Custom Filtering

• filteredItems and filter can now be used to bypass the built-in client-side filtering

<vaadin-combo-box filtered-items="[[filteredItems]]" on-filter-changed="_filterChanged">
</vaadin-combo-box>

<script>
  ...
  _filterChanged: function(e) {
    var filter = e.detail.value;
    this.filteredItems = elements.filter(function(el) {
      return el.indexOf(filter) === 0;
    });
  }
  ...
</script>

Remote Filtering

• loading can be used to place a loading spinner while new filteredItems are being fetched async

<iron-ajax url="http://example.org/?filter=[[filter]]"
           last-response={{response}}
           loading="{{loading}}"
           debounce-duration="500" auto>
</iron-ajax>

<vaadin-combo-box filtered-items="[[response]]" filter="{{filter}}" loading="[[loading]]">
</vaadin-combo-box>
