Title: Avoid having an ng-if if mutiple:

https://github.com/angular-ui/ui-select/issues/217 - Is there any way to change multiple selection mode at the run time?

Instead of the accessor (in case something needs to be modified) - how about this:

{{$select.match.fields[espLookupCtrl.displaycolumn]}}
