The MultiSelect cannot be configured to display selected items separated with comma. Such behavior is implemented for the AutoComplete
widget. In the MultiSelect the selected items are displayed as tags. The mentioned tagTemplate
option allows you to customize the content of the tags and cannot be used to remove the tag and display only the items text separated by commas. We would suggest logging your idea as a feature request in our Feedback Portal
. If approved by the team, it will be implemented in a future release.
