hi,
how to provide a blank option in the select drop down list for the user to select.
Such option can be set to the richselect and combo with the$empty
flag:

Behavior of ui.select is similar to the regular HTML select input, so the options have to be modified before init, or
select.config.options.unshift({id:"", value:""});
select.refresh();
