When I was editing a custom field I got this pop-up:
'Obsolete widget The old "Advance Multi-Select" widget is being phased out and will be removed in a future version of CiviCRM. "Multi-Select" is the recommended substitute.'
Our user find it quite nice to be able to move items between the two lists rather than remember to hold down the Ctrl key or else they lose all their previous selections.
Can anyone shed any light on why this field type is going obsolete and if there is any way of continuing to use something similar?
Had a search around and couldn't find any info.
