Hide component

Hi, Is there any way to hide a component while another component is shown?
for example, in my app, I have a list collection to display a list of grades for one student. I have now added a Hint component that says ‘no grades available’ and want to show the Hint component only when there are no grades for that user.

Use a rollup column to count the number of grades, then use the result of that to drive the visibility of your hint component. ie. only show it if the count is zero.
