Fixed an issue where the clear buton of the single selection wouldn't disapear

- Added Client Side Functionality if the number of records returned is smaller than the limit set by the dev, the component will work using client side (without going back to the server to fetch more data).

- Added a size option so that the developer can easly set an appropriate size for the Selected pannel
