Filtering

Filtering allows to filter the collection of cards from e-data-source.bind which meets the predefined query in the quick filters collection. To enable filtering, define e-filter-settings.bind 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
  • <template>
      <div>
         <ej-kanban id="Kanban" e-data-source.bind="KanbanData" e-key-field="Status" e-fields.bind="Field" e-filter-settings.bind="filterSettings">
           <ej-kanban-column  e-header-text="Backlog" e-key="Open"></ej-kanban-column>
    	   <ej-kanban-column  e-header-text="In Progress" e-key="InProgress"></ej-kanban-column>
    	   <ej-kanban-column  e-header-text="Done" e-key="Close"></ej-kanban-column>
         </ej-kanban>
      </div>
    </template>
