Hello - is there a “notifier” (android component) equivalent for iOS - I am trying to use the Web API component to call a URL if certain fields are met - if not I want to show a popup message. Also, on List Viewers: are search filters enabled in List Views by default? Which blocks do I use to set the display text to whatever a user selects from the list? The android version of Thunkable has a ListVier.Selection option that I cannot seem to find in the iOS version. Thanks! ---

Hi there. We don’t yet have notifiers but thanks for your request. We will add it to our list of feature requests. The Listview itself does not yet have a search filter enabled but you can select from a list. The block below saves your selected item to a Local Storage database and sets the Button text to that selection. ![](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/2X/6/60c5c73375f1be6d2975e26056f5f362841f4a1b.png) Hope this helps!
