Hello,
When you click on a sub-category, the filter will display only the products within that category and will automatically adjust to show only the filters that are relevant to it.
For the attributes (such as color, size, brand, etc.), by default the theme hides filters that don’t apply to the current selection. If you’d like all attribute filters to remain visible even after applying one, you can adjust this in the widget settings.
Please go to Appearance > Widgets, expand the WoodMart WooCommerce layered nav widget, and set the Query Type to “OR”. This will ensure that the attribute filter headings (like Color, Size, Brand, Condition, etc.) remain visible regardless of what has been selected.
