Cascading Lookup Plus Field Type

Cascading Lookup Plus Field Type is a handy extension that is designed to help certain users extend the functionality of SharePoint and allow developers to easily integrate new functions into their projects.

This component enables the use of cascading fields, allows two-way lookup as well as cross-site and filtered queries. With Cascading Lookup Plus Field Type it is also possible to filter out the items which are included in the lookup field. This can come in handy whenever you want to create a series of fields where each entry filters the next one. An example for such a feature would be "Region," "Country" and "City" fields.

Lists can be linked by using a two-way connection module, similar to other database software solutions, thus making users able to create dual lookup fields. Whenever users create a lookup from one list to a different one, the reverse of that lookup is created as well. The link between two distinct entities can be managed from any side of the connection.

An example for the two-way connection's applicability is when users create lookup fields that connect each item to another entity in another field, a reverse lookup will be created on the spot in the second field.
