 Or you can even do it the other way round setting C<multiple> to 1 on creation
 and open a single selection popup with js.
 
+If C<%params> contains C<multiple_limit> the alternative popup will not
+show any results if there are more than C<multiple_limit> results. A warning

 Obsolete parts will by default not be displayed for selection. However they are
 accepted as default values and can persist during updates. As with other
 selectors though, they are not selectable once overridden.
