By default, the Search Results Widget shows categories/collections that match the search term.
To hide categories/collections from the widget, follow these steps:
- Go to the Smart search & Filter control panel > Search results widget section > Content tab > Categories part.
- Set up 0 in the Categories per page field.
- Apply the changes.
That's all. The categories/collections tab won't be shown in the widget. You can go to your storefront and check it out.
