I changed your post to format your code or error message correctly. Please use the </> button above the post input field to format your code or error message or wrap it in ``` (“code fences”) manually. This will make sure your text is readable and if it recognizes the programming language it also automatically adds code syntax highlighting. Thanks.
Problem was one I slide one list option and not close and open second list option the last one still open not closed automatically. See the picture you will understand. My mistake was loop in ion-list so I changed it into <ion-item-sliding *ngFor="let project of Projects">
so its working
