Multi-Select question

I have the following scenario and looking for some guidance on how to address this. I have a page with 3 reference selectors. Selections in these 3  control display of data(constrained by) in a Reference set selector that is displayed on the page.  I have all of the above data available on my context object. However, my requirement is that user should be able to multi-select in one of the reference selectors that control display of data in Reference set selectors Looks like I can only select one in the reference selector and no multi-select available.  I tried few other things with no success so far. I appreciate any suggestions/guidance. Thanks in advance, Manyam

Have you tried the Simple Check Box Set Selector or the Checkbox set Selector (Table) widgets from the app store? Might help with what you are trying to do.
