How do i make elements in list view clickabel?

Hello everyone I used this list view to create a list with many elements and a search bar to look for elements in the list view. For some reason the list doesn’t appear unless I write something in the search bar so I hope some knows a solution so that the all elements appear as default. Also I need that the elements in the list are clickable and that when they are clicked they send me to another screen. Any help or recommendations is much appreciated. Thanks in advance
