Filter type setting controls how the filter items become selected. There are 5 built-in filter types in our Woocommerce products filters plugin: single item selection, multiple items selection, range selection, string search, and dates selection.
If you have more than one annasta Filters presets working on the same page, make sure that the same taxonomies are associated with the same filter type (for instance, if you have Product Categories filter in 2 different presets displayed on the same page, make sure they are either single-, or multi-select Filter type in both cases). In case of the range filters it is also advised to have the multiple range filters’ scales match.
Whenever you change the Filter type and wish for the previews to reflect the change, hit the Save changes button at the bottom of preset.
