How to implement the multi-selection with angular either checkboxes / selectbox

Can any one please suggest me the helpful directive to implement the feature with multiselection.

The i/p as array format. eg: [1,2,4,5,6,7,8,9]

I used the below directives, - angular ui.select : When I save it, sends the strings correctly. But When i get this values the select box is select with commas. - checklist-model : Saving properly. Get the value is coming as single string.

eg:

items = [1,2,3,4,5,6,7] Save: [4,6] Get : 4,6 (selected as 3 items)

sorry for incorrect english words.
