Picker has a addValue method?

On the "Picker" page of the documentation, there is also addValue in the method list:

framework7-website/src/pug/docs/picker.pug

Lines 347 to 349 in 2f3a2d7

    
           tr 
        
             td picker.addValue() 
        
             td Adds value to the values array. Useful in case if multiple selection is enabled (with `multiple: true` parameter)

But this method doesn't seem to exist in

https://github.com/framework7io/framework7/blob/master/src/core/components/picker/picker-class.js

	tr
	td picker.addValue()
	td Adds value to the values array. Useful in case if multiple selection is enabled (with `multiple: true` parameter)
