AQB Soft

This module allows to create a so called "#conditional #fields". I.e. a fields which appear only if a certain value is selected in another field.
A very common example is a Gender specific fields. For example if for a Gender is the "Man" selected then the field "Mustache" appears. Otherwise the field remains hidden. Or for example you can have a switcher "Job" which, when checked, shows a few job related fields, and when it is unchecked then all job related fields remain hidden.

Any customizable #form in UNA can be extended with this module and have conditional fields on it. I.e. Persons, Organizations, Posts, Discussions - literally any form can have conditional fields with this module.

The fields of the following types can be selected to determine conditions: select, radio set, checkbox, switcher
The fields of any type can be used as a conditional field. The only limitation though is that conditional fields can not be Mandatory.

This module allows to create a so called "#dependent #fields". I.e. a dropdown-like fields in which the available options depends on a selection in another field. A very common example is a Category->Subcategory. So when a certain #Category is selected - the #Subcategory field shows only options related to a selected category. There could be a lot more use cases for dependent fields such as Country->State->City or City->School.

Any customizable #form in UNA can be extended with this module and have dependent fields on it. I.e. Persons, Organizations, Posts, Discussions - literally any form can have dependent fields with this module.

Note that the module affects only the "select" type of fields (dropdowns).
