Hi Mario,

Query: How to prevent duplicate items/tokens from being selected in the Combobox

Already we provided the IsSelectedItemsVisibleInDropDown property to restrict the duplicate items shown in the dropdown. Below is the code snippet.

<combobox:SfComboBox 

                             MultiSelectMode="Token"

                             IsSelectedItemsVisibleInDropDown="False"

                             HeightRequest="40"

                             DataSource="{Binding EmployeeCollection}"

                             DisplayMemberPath="Name" />

We have prepared a new sample for your reference and please get it from the attachments. Please let us know if you need any other details.

Regards,

Shivani
