Hi to all,
i'm sorry 4 my bad english.
This is the scenario:
A multicheckbox field named cb_categorie
For each checked checkbox i would show 2 new multicheckbox fields
cb_giorni (weekday's list)
cb_orario (mornig, afternoon, night, late night)

Site's administrator can add more items on cb_categorie.

All fields must be searchable.

How can i do?

thanks

You understand me correctly.
I've installed CB Conditionals.

Every time administrator adds a new category he must adds 2 extra fields for cb_giorni and cb_orario?

How can i set the conditions for display right fields based on user's choice?

example

cb_categorie:
Tennis
Jogging
Soccer
Baseball

hidden fields:
cb_giorni[Tennis]
cb_orario[Tennis]

cb_giorni[Jogging]
cb_orario[Jogging]

cb_giorni[Soccer]
cb_orario[Soccer]

cb_giorni[Baseball]
cb_orario[Baseball]

When user check Tennis in cb_categorie the fields
cb_giorni[Tennis]
cb_orario[Tennis]
must be visible


When user check Jogging in cb_categorie the fields

cb_giorni[Jogging]
cb_orario[Jogging]
must be visible

etc etc

In profile page, users can modify their choices.

All choices must be searchable by a custom form.

I used many single category fields and make other subfields conditionals with CB Conditionals.

categories:
cb_Tennis (singlecheckbox)

hidden fields:
cb_giorniTennis (multicheckbox) -> (cb_Tennis == 1)?show():hide();
cb_orarioTennis (multicheckbox) -> (cb_Tennis == 1)?show():hide();

categories:
cb_Jogging (singlecheckbox)

hidden fields:
cb_giorniJogging (multicheckbox) -> (cb_Jogging == 1)?show():hide();
cb_orarioJogging (multicheckbox) -> (cb_Jogging == 1)?show():hide();
