I want to filter a visual based on a specific field “Flight Number”. I want to use a parameter though, because later, I want to expose the parameter value (selected from filter control) in a text box.
I follow steps below but the control does not provide the option of a multi select drop down list. Is there a way to achieve this?
-
I create a parameter, string and click on Select “Multiple values”
-
Add Control: Select “Control” to create a control for your parameter
-
- Style: “Dropdown multiselect” (this allows multiple selections)
-
Link to dataset field: Select my dataset and the “Flight Number” field
-
Then I create a filter but the only option available that allows to link it with a parameter is if I choose “custom filter”. I create it but then my only option is just to fill in the control a single value and not a multi select from a drop down list
