How i can turn off autocompletion in Extjs combobox?

When I selected some item in combobox and then I'm开发者_开发百科 trying to select another item in same combobox, I can see only one item - those which is selected right now. I believe that happens because of autocompletion. Does anybody know how I can disable it or something. I need to see all values on each click, regardless if something was selected already or not.

Add triggerAction:'all' to your config.

better add disableKeyFilter:'true' to your combo box
