MenuItem onClick

SmartClient Version: v9.1p_2014-08-28/Pro Deployment (built 2014-08-28)

Hello,

I have an IconMenuButton, using a Menu with multiple MenuItem's (including sub-menus) and I would like to allow the client to click/check multiple MenuItem's without the menu closing after each click/check.

Essentially, I am looking for the same behaviour the List Grid provides when using the "Columns" menu to select columns from the header context menu.

Can you please recommend the best practice for this please?

Thanks.
