Hi everybody, I had a performance issue while doing live-search in a list of 7000 cities. My solution might interest all guys who are facing the same problem. ![searchinlist](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/c/7/c73f1f7fe2bf1af76b330c7e1e159f1aeb929fbb.png) You cannot read the blocks because of the resolution of the PNG but you can see them in my public project ( of course you have to put a citylist in the variable for yourselft because sharing will erase my firebase login data): [Thunkable](https://x.thunkable.com/copy/1cb7e31daf92404614196ccca4194e54) ---

Hi, Sorry, but I did not understand. I have over 20,000 city names and I didn’t notice big brakes live-search (line search for the most recent cities in the list takes 1-2 seconds). “I had a performance issue” - what is the problem? ---
