[Design]-How to create a drop list in Adobe XD?

Hello, 

I have a basic question on ADOBE XD.

I created a field, an when clicking on it, I would like a dropdown list to appear.
I've done an animation but my droplist shape drops from the top of the screen and not from the field i created. How can I allow it to drop down directly from my field?

Here is a screenshot to show you how it's linked so far:

Thank you for your help.
