Currently the kengoMultiSelectSummaryTag only supports a number as its input, which enables switching to summary mode if the number of selected items is greater than the specified value.

It would be nice to add an option for dynamic mode which will be based on the available space for the control and will automatically switch to summary mode if there is not enough  space for displaying all the items.

See the screenshots to illustrate how it might look like.

Thanks,
