I don't understand what you're trying to do. I'm, sorry. Have you read and followed the docs? you don't need to hardcode links or worry about urls. The blog components do that for you. You shouldn't need to worry about filters unless you need some sort of specific link. But again, if you are using the categories component, it generates those for you. You seem very confused. Please read through the docs slowly and carefully.
ya, sorry. i am bit confuse and have read the document. I have set only Blog Search Page to the main blog page. But the url is still showing the default blog page url.com/blog instead of url.com/category/categoryname.
May I know what went wrong? really need some help here. Thanks.
