Tag Box

Tag Count Limitation

Documentation

The TagBox allows you to limit the number of displayed tags. When specified limit is exceeded, the tags are united into a single multi-tag displaying the number of selected items. The TagBox can display multi-tag alone or along with ordinary tags depending on the showMultiTagOnly option value.
