This is not complete, if we are going to implement Field Dependency on the ticket view, we should implement it in Agent Portal as well.

It should filter the select fields / link fields similar to how it is done in the "New Ticket View"

It is there on agent portal, see the sub category is hidden automatically

[RitvikSardana]

I mean the options are not filtered, of Select and Link fields

[trufurs]

@RitvikSardana
i agree with you,
i can take that in another pr , fixing the filters bug similar to the way it is done in new ticket view.
or if you want i will do it one PR (new PR) fixing commit message errors.

[RitvikSardana]

please make this work with Agent Portal & Custom Portal both

it should only work if we have a setting enabled

"Apply Field Dependency in Ticket View"

if this is enabled, then only these filters should apply in Ticket View.
By default it should be disabled.

This setting should exist in HD Settings in backend and in "General" in Frontend settings

@RitvikSardana
i see this field dependency issue of not using display on on agent portal -mobile view as well but it currently works on agent portal desktop view
so should i add 2 fields
Apply Field Dependency in Customer View
Apply Field Dependency in Agent View

or
Apply Field Dependency in Ticket View -> only
and i also change the current desktop view to evaluate only if this is enabled ?

can you please guide me with a simple requirements and what should be the end result ?
also i started working on filter table dependency for parent child in agent portal ( i will make separate PR for it , or if you want in one i can do that)
