Hello,
Firstly, under the WoodMart Theme to access the Filters area Settings you can go to Dashboard >> Theme Settings >> Product Archive >> Shop Filters >> there you can enable or disable the Filters and also select their Content Type.
There are two options for its Content Type (Widgets or HTML Block): https://ibb.co/hYrJnnH
If you select the Widgets > then you need to go to Dashboard >> Appearance >> Widgets >> there you can add the widgets under the Shop Filters area: https://ibb.co/wBXGM4Q
If you want to add the Attributes created on your Site, then you can add the Theme’s widget “WOODMART WooCommerce Layered Nav” > in that you can select the Attribute created.
Or the second way is the HTML Block. You can go to Dashboard >> HTML Blocks >> create a Block with Page Builder active on your Site >> and then use that Block as Filters area by selecting that Block under the Dashboard >> Theme Settings >> Product Archive >> Shop Filters.
Further, there isn’t an option or widget available to Filter Products by Labels. So, alternatively you can add the Attributes for Filters. If you want, you can create the Attributes for your Labels to > use them under the Products > and then you can use that Attribute in the Filters area by using the Theme’s above defined widget. This is the best possible right now.
Hope this helps !
Best Regards
