I'm not sure if you'll like this behaviour, but if you change the action to run on "Select" rather than "Menu" then the link isn't displayed at all - it is simply activated when you click on the item.
If i am right you want to remove the Rome right,
Go to the sheet --> Click on Tooltip in Marks section --> Remove the field from there and let it be blank so that whenever you hover you can see only the URL not "Rome"
hope this helps kindly mark this answer as helpful or correct so that it will help others
I agree with what Stuart said. Mainly because you are clicking on the City Name to activate the URL, I am highly doubtful you will be able to hide the name on clicking the box.
If you want to hide the name from the tool-tip its pretty straight forward -> Tooltip in Marks and remove City.
Soham Wadekar + Naveen B I apologize. I should have specificed in my original post that the tooltip box is already empty. That is why I am stumped! There is no text in the tooltip box nor is there anything on the marks card besides the link being on detail, (which is required for the url action)
Stuart Fieldhouse -- you are correct. I wan't to keep the URL action as Menu and not Select. Thanks anyway.
Have you unchecked the "Show Tooltips Box" inside the tooltip?
