Hide question title in dashboard

I put a question in a dashboard but want to hide the name of the question. Could you please let me know what I need to do?

Hi @williamvu
You can change the card (the questions on dashboards) visualization settings and changing the name to a single space.

Thank you @flamber.

This is not working now. You can't set and empty space as the name of the question or the dashboard.
Do you have any other solution to this problem?
