Hello Hristo,
if the JSON data is loaded from the server into the DataAdapter via URL, the selection with the mouse does’nt work. In the example, the contact name is to be entered. You enter one or more letters and a list of hits is displayed. If you now want to select an entry from this list with a mouse click, it does not work. You can only use the arrow keys and the tab key.
