In this case  myvar should be a boolean value  If this variable is true  it will show the div  if it s false   It will hide   Check this out

To clarify  the above example does work  my code in the example did not work for unrelated reasons    If myvar is false  null or has never been used before  i e   scope myvar or  rootScope myvar never called   the div will not show  Once any value has been assigned to it  the div will show  except if the value is specifically false   The following will cause the div to show    scope myvar    Hello World     or   scope myvar   true    The following will hide the div    scope myvar   null    or   scope myvar   false
