How to make a contextual filter optional I'm making a contextual filter, to pass along an argument from a panel to a view, using Content: Has taxonomy term ID.

This is so that it pulls in a keyword from a URL.

However, I want it to work so that when no keyword is passed in, it goes based on the last URL parameter.

For example:

www.example.com/tech/startup

It should pull ONLY things with both tech and startup if this is passed.

However, if the URL is just:

www.example.com/tech

Then it should show ALL articles with the tech taxonomy term.

How do I do this?
You can use Exceptions setting in views like below



And point your menu link to www.example.com/tech/all instead of www.example.com/tech
