How to hide the list to force user to use the search bar to show items?
Can you elaborate a little bit please and provide some context?
A screen shot that demonstrates what you are trying to achieve would be helpful.
You can add a text entry to serve as your search bar.
Then add an inline list and filter the inline list by that search term.
Add an If Then Else column: Let’s say, you put the logic in this correct top-down order: if search term is empty then return empty, if search term is included in Place Name then true, if search term is included in Address then true Only items that return true for that if then else column should show up.
When it’s empty, nothing is shown since we already have a logic in place that returns nothing when the search term is empty.
