title: Filtering multiple columns in Google Sheets
body: <p>I'm trying to filter multiple rows and columns in Google Sheets and show only the cells that match the value that I want, but so far I didn't have success.</p>
  <p>Here goes a link with the raw data and the expected output that I need.
  <a href="https://docs.google.com/spreadsheets/d/1355FJBYlzlU1RajWZ1Cj1qhXkRrU4QYegeQ4UzBeE3I/edit?usp=sharing" rel="nofollow noreferrer">https://docs.google.com/spreadsheets/d/1355FJBYlzlU1RajWZ1Cj1qhXkRrU4QYegeQ4UzBeE3I/edit?usp=sharing</a></p>
  <p>In this example, I wanna filter by activity and show only the days that I have a &quot;Cycling&quot; class, for instance. The filter needs to be a sort of dropdown since more people will be using it.</p>
  <p>I tried to use the slicer feature, but it allows me to filter just 1 column and not multiple.</p>
  <p>Any idea on how to make it?</p>
