Hi Maria,
Greetings from Syncfusion.
We would like to let you know that the `Placeholder` can be set using the Watermark property in SfComboBox as per in below code snippet.
Code Example [XAML]:
<combobox:SfComboBox HeightRequest="40" Watermark="Enter 'A' to filter suggestions" /> |
Please check with the above and let us know if you have any concerns.
Regards,
Hemalatha M.
