controller class
 
01public class CategorySearchController {
02 
03    // the results from the search. do not init the results or a blank rows show up initially on page load
04    public List<categoryWrapper> searchResults {get;set;}
05    // the categories that were checked/selected.
06    public List<categoryWrapper> selectedCategories {
07        get {

21    }
22 
23    // constructor

31        } else {
32            searchResults.clear(); // clear out the current results if they exist

39         
40        for(account c : Database.query(qry)) {
41            //new wrapper by passing it the category in the constructor
42            CategoryWrapper cw = new CategoryWrapper(c);
43            // wrapper to the results
