Going to try and put this as simple as i can.
Lets say i have 2 Entity Reference Fields A and B.
A) Gives a list of Countries.
B) What ever country was selected in A should only display list of available State/Province's to that country
Example: Lets say i have a content type of Countries where i can save the country name in the title, then i also have a content type of state/province's where the state/province name is saved in the title with entity reference field where a county can be selected for that State/Province.
Lastly i have a content type user information, where a user can enter his/her name in the title, a entity reference field country and another entity reference field state/province. When the user select, lets say, USA as a country in the first entity reference field, the second one should only display a list of sates available in the USA.
Can something like this be done where the option of one Entity Reference field can be used as a filter for another entity reference? and if so, how can something like this be achieved? any and all help is much appreciated.
