Hi,
To add a filter in the sidebar in WoodMart WordPress theme, you can follow the steps below:
Login to your WordPress dashboard.
Go to Appearance > Widgets.
Find the widget and drag it to the desired sidebar area.
Configure the widget settings, such as choosing the taxonomies and attributes you want to include in the filter, as well as the title and display options.
Save the widget and refresh your website to see the filter in action.
This widget area is for the Shop / Product categories pages. WooCommerce filters and Product categories should be added here. In order to show the sidebar on the Shop page, it is necessary to set “Right” or “Left” in the Theme Settings – > Shop – > Sidebar
