Features of BoxSelect

BoxSelect is an extended ComboBox component developed for more intuitive multiselect capabilities. BoxSelect comes with lots of examples and proper documentation. The following features are provided by the BoxSelect extension:

  • Selected items can be removed individually.

  • Customizable item templates for controlling the display of the selected values.

  • Supports keyboard-based selection and navigation for the selected values.

  • Supports on-demand loading of values from remote stores when an unknown value is set, and the queryMode option is set to remote and forceSelection is set to true.

  • Setting forceSelection to false creates new records.

  • When multiSelect is set to true the pick list can be configured to tell if it should collapse or not, after making a selection.

  • Selected items can be configured to be stacked or autosized.

  • Most of the existing functionalities and configuration options of ComboBox should work with BoxSelect.
