Since the opening of this post, you now offer this module. This EasySocial Custom Field Search module is a good start
However, its use is very limited.
- This module only works with Dropdown fields
- We must select a category in the parameters
- Conditional Custom Fields are not supported
- Results are not displayed directly in the listing (Ajax)
With support of the Conditional Custom Fields, this would be ideal.
If for example I select "Fruits" in the first Checkbox, a second Dropdown or Checkbox will be displayed with the choices : "Banana, Strawberry, Apple, etc.".
Whereas if I select "Vegetable" in the first Checkbox (or Dropdown), it will automatically display a second Dropdown or Checkbox with the values "Carrot, Leek, Tomato".
The form would then be dynamic, intelligent : Conditional Custom Fields Search.
