Filtering

Filtering allows to filter the collection of cards from dataSource which meets the predefined query in the quick filters collection. To enable filtering, define filterSettings collection with display text and ej.Query.

You can also define display tip to describe filter definition to user using property description. If the description property is not defined, given text will act as display tip.

We can also customize filter option through external button or customToolbarItems by using filterCards() method.

The following code example describes the above behavior.

  • html
  • <?php
        require_once '../EJ/AutoLoad.php';
        ?>
        <div class="cols-sample-area">
        <?php    
        $Json = '[{"Id": 1, "Status": "Open", "Summary": "Analyze the new requirements gathered from the customer.", "Type": "Story", "Priority": "Low", "Tags": "Analyze,Customer", "Estimate": 3.5, "Assignee": "Nancy Davloio", "ImgUrl": "Content/images/kanban/1.png", "RankId":1 }, { "Id": 2, "Status": "InProgress", "Summary": "Improve application performance", "Type": "Improvement", "Priority": "Normal", "Tags": "Improvement", "Estimate": 6, "Assignee": "Andrew Fuller", "ImgUrl": "Content/images/kanban/2.png", "RankId":1 }, { "Id": 3, "Status": "Open", "Summary": "Arrange a web meeting with the customer to get new requirements.", "Type": "Others", "Priority": "Critical", "Tags": "Meeting", "Estimate": 5.5, "Assignee": "Janet Leverling", "ImgUrl": "Content/images/kanban/3.png", "RankId":2 }, { "Id": 4, "Status": "InProgress", "Summary": "Fix the issues reported in the IE browser.", "Type": "Bug", "Priority": "Release Breaker", "Tags": "IE", "Estimate": 2.5, "Assignee": "Janet Leverling", "ImgUrl": "Content/images/kanban/3.png", "RankId":2 }, { "Id": 5, "Status": "Close", "Summary": "Fix the issues reported by the customer.", "Type": "Bug", "Priority": "Low", "Tags": "Customer", "Estimate": "3.5", "Assignee": "Steven walker", "ImgUrl": "Content/images/kanban/5.png", "RankId":1 }]';
        $Json = json_decode($Json,true);
        $kanban = new EJ\Kanban("default");    
        $column = new EJ\Kanban\Column();
        $column ->key("Open")->headerText("Backlog");    
        $column1 = new EJ\Kanban\Column();
        $column1 ->key("InProgress")->headerText("In Progress");    
        $column2 = new EJ\Kanban\Column();
        $column2 ->key("Close")->headerText("Done");  
        $filterQuery = new EJ\Query();
        $filterQuery->where("'Assignee','equal','Janet Leverling'");
        $filterQuery1 = new EJ\Query();
        $filterQuery1->where("'Status','equal','Close'");
        $filter = new EJ\Kanban\FilterSetting();
        $filter->text("Janet Issues")->query($filterQuery)->description("Displays issues which matches the assignee as Janet Leverling");
        $filter1 = new EJ\Kanban\FilterSetting();
        $filter1->text("Closed Issues")->query($filterQuery1)->description("Display the issues of 'Closed Issues'");			
        $fields = new EJ\Kanban\Field();
        $fields ->content("Summary")->primaryKey("Id")->tag("Tags");
        $filterSettings = array( 
        $filterSetting,$filterSetting1);    
        $columns = array( 
        $column,$column1,$column2);    
        echo $kanban ->columns($columns)->filterSettings(array($filter,$filter1))->dataSource($Json)->fields($fields)->keyField("Status")->render();
        ?>
        </div>
