Is there an extjs 3.4 plugin that will allow a combobox to have multiselect functionality and allow the options to be listed by grouping? Kind of like this jquery plugin: http://www.erichynds.com/examples/jq...mos/#callbacks/. I didnt want to reinvent the wheel if I didnt need to.
I've found some plugins that may be helpful but they all either support multiselect or grouping not both.
Any help is greatly appreciated.
