In some cases, you want just the marker without the tooltip. While this is not a default option in the widget editor, you can do this by adding some custom CSS to the widget.
If you haven't created a widget before, you can learn how to do this here.
Step 1: Create a new widget
Create a new widget of the type "Small tag with a small tooltip".
Step 2: Add the custom CSS code
You can copy and paste this code. Make sure to turn on advanced CSS to see your changes.
Now you won't see the tooltip anymore, even when someone hovers it!
Please be aware that the interaction event will still get logged whenever someone hovers over it.
