Multi Choice List having hierarchy

[vdeamicis]

Hi,

I need to collect a field in my Catalog item form. This field must be a multichoice list whose choices are specified following a hierarchy. The user while selecting choices in the multi choice list field shall be able to see the following:

• Item 1
• Item 1.1
• Item 1.1.1
• Item 1.1.2
• Item 2
• Item 2.1
• Item 2.2
• Item 3
• Item 4
• Item 4.1
• Item 4.1.1

and select multiple items from whatever levels.

For instance, the user shall be able select: Item 1 and Item 2.1 and Item 4.1.1.

The maximum number of levels of the Hierarchy is 3.

Do you have some hints on how to implement this.

Thank you and Kind regards,

Valentina
