Which one should come first after 'What do you think'? Subject or be verb?

[Bright Sunny]

I get confused when I make a question starting with 'what do you think'.

I remember I learned that I have to put 'subjective' first before 'be verb' because it requires an answer more than 'Yes' or 'No'. However, I have seen people saying 'be verb' first as if it was just like other question starting with 'What is'.

For example, could you tell me which one is right?
-What do you think the most important thing is in your life?
-What do you think is the most important thing in your life?

It would be appreciated if anybody could help me out on this. Thank you in advance.

Don't forget that you will also hear "What do you think the most important thing in your life is?"

Thanks for your advice. Do you mean all of three are all correct and are frequently used?

You will hear all three used.
