JET Selector

Description: A checkbox to support selection in Collection Components

The oj-selector is a component that may be placed within a template for Table, ListView. It presents as a checkbox when the Collection Component is configured for multi-selection. Note that the selector does not prevent click events from bubbling up to the containing element. In cases where an application wishes to prevent the containing element or component from performing a default action based on these click events, the application must ensure the appropriate updates are made (ie. setting the data-oj-clickthrough='disabled' attribute on a selector within an that does not include an ).


<oj-list-view id="listview"
     data="[[dataProvider]]"
     selected="{{selectedItems}}"
     selection-mode="[[selectedSelectionMode]]"
     scroll-policy="loadMoreOnScroll">
 <template slot="itemTemplate" data-oj-as="item">
   <li>
     <div class='oj-flex'>
       <div class="oj-flex-item">
         <oj-selector selected-keys='{{selectedItems}}'
                       selection-mode='[[selectedSelectionMode]]'
                       row-key='[[item.key]]'>
         </oj-selector>
       </div>
       <div class="oj-flex-item">
         <span data-bind="text: 'Name '+ item.data.name"></span>
       </div>
     </div>
   </li>
 </template>
</oj-list-view>
