Tag Count Limitation
Documentation
You can use the maxDisplayedTags property to limit the number of displayed tags. When the specified limit is exceeded, the tags are combined into a single multi-tag that displays the number of selected items. Use the showMultiTagOnly property to specify whether to display a multi-tag only or other tags as well. You can also use onMultiTagPreparing event handler to customize the multi-tag, as shown in the second example.
