Multi-Select Option Sets Missing setVisible() for JavaScript (Workaround)

It is common practice in Microsoft Dynamics 365 to use Business Rules to show and hide fields on a form.  But, with that addition of multi-select option sets, you can't do this.  So the next logical step is to use JavaScript.  There is just one small problem, there is no setVisible() function for multi-selection option sets.  Here are the controls we do have access too, as of this post:

So, how can we dynamically show / hide multi select option sets?  The easiest way is to use a section.  Place a new section on you form.  Then you will need to use JavaScript to get the tab and section by name.  Once you have that, you can dynamically show / hide the section to make the multi-selection option set show and hide.  Here is an example of the JavaScript:

 function ShowHide(executionContext)  
 {  
   //Create the form context  
   var formContext = executionContext.getFormContext();  
   var contactStatus = formContext.getAttribute("Field Name").getValue();  
   var tabObj = formContext.ui.tabs.get("Tab Name");  
   var sectionObj = tabObj.sections.get("Section Name");  
   if (contactStatus === 1)  
   {  
     sectionObj.setVisible(true);  
     formContext.getAttribute("fieldName").setRequiredLevel("required");  
   }  
 }
