Hi,
Thank you for your reply,
Actually I used "filter" alternative forms before to create custom filtering for custom tables (data tab) exactly as described in the
developer docs here, yet I am not sure this will work in my case (maybe I am wrong).
Basically what I wanted to achieve is creating custom filter forms in CMS Desk --> Listing Mode, when clicking on certain Page Menu Items or Folders in the tree. For example, if I have a folder in the tree named "clients" containing items of document type "cms.clients", if I click on the Folder and go into the listing mode, there will be a default filter and a UniGrid displaying the documents under this folder, the filter will be only targeting the Documents Name and Types, what I wanted is a filter based on Columns of the Clients Document Type (Name, Address, Phone, etc...).
As I described in my Blog post shared previously, I was able to achieve that with some customization.
Thanks,
