Blox drop-down with 'All' selection

Here is a solution to create dropdown filter using blox which contains an additional 'All' element to filter all item in the column.



Steps:

  1. Create new Blox widget and add a dimension under 'items' panel. Add same dimension as a dashboard filter.

2. Add below Blox script. Replace the name 'Region' in below script with the name of dimension you added in the above step.

                                                "filters": [
                                                    {
                                                        "filterName": "Region",
                                                        "filterJaql": {
                                                            "explicit": false,
                                                            "members": [
                                                                ""
                                                            ]
                                                        }
                                                    }
                                                ]
                                            }
                                        }
                                    ]
                                }
                            ]
                        }
                    ]
                }
            ]
        }
    ],
    "actions": []
}

3. Add below widget script. This is to add 'All' in dropdown.


widget.on('processresult', function(se, ev){
	allObject = [{
					"Panel": "Region", //replace region with name of item panel added in step 1
					"Value": "All",
					"Text": "All",
					"HasValue": true
				}]
	
	ev.result.unshift(allObject)
})

4. Create a custom action 'dropdownFilter' using below script.





if(payload.data.filters[0].filterJaql.members[0] == "All")
{
    filter = {
        "explicit": false,
        "multiSelection": true,
        "all": true
    }
}else
{
    filter = {
        "explicit": true,
        "multiSelection": true,
        "members": [
            payload.data.filters[0].filterJaql.members[0]
        ]
    }
}

dashboardFilter = prism.activeDashboard.filters.$$items.find(el => el.jaql.title == payload.data.filters[0].filterName)

var filterOptions = {
    save: true,
    refresh: true,
}
dashboardFilter.jaql.filter = filter
prism.activeDashboard.filters.update(dashboardFilter, filterOptions)
