Hi Mirnalini, sorting parameter values with controls are not possible in Quicksight now. Please refer to this thread: Can we sort the dropdown values of a string parameter control that is inked to a dataset field?
You can add these taxonomy levels to the dataset as a “Taxonomy” column. Add an Taxonomy parameter in Quicksight and create a control, link this parameter to Taxonomy column. Then you’ll be able to select multiple values of the taxonomy level to control your visual.
