the SelectDialog widget does not include any inbuilt search logic as of now unlike the TableEnhanced widget, so indeed this matches the expected behaviour. Also, the native OpenUI5 SelectDialog control does not offer this functionality per standard, but you would have to individually add the logic via JavaScript code that gets executed when the ‘search‘ and / or ‘liveChange‘ events fire. Here you can find a sample application from SAP demonstrating how to add search logic to the SelectDialog by registering a specific event handler.
If you would like to request an enhancement of Simplifier’s SelectDialog widget to offer a generic inbuilt search functionality, you can do so via our Ideasportal.
