I am trying out the custom fields which are working great so far. However what I would like to be able to do is to have a custom field for which the content varies depending on the content in another custom field (or a standard field, such as category). For instance if the value in list box A is "X" then "X1", "X2","X3" are displayed in list box B and if the value in list box A is "Y" then "Y1", "Y2","Y3" are displayed in list box B.
Ultimately what I want to be able to do is to use the event filter module so that a user can select something in list box A and the values in list box B change and the results of the filter match the criteria selected.
Is this possible, even as a paid option?
Thanks
