Customer portal shows empty/irrelevant custom fields; no conditional field visibility in HD Ticket Template

[ews-pgasser]

Information about bug

Problem
HD Ticket Template has no way to conditionally show/hide a field based on another field's value. Every field in a template's fields table renders on the customer portal ticket detail view regardless of relevance, showing "—" for fields that don't apply to that ticket's category/type.

Where
TicketCustomerTemplateFields.vue renders ticket.data.template.fields filtered only by hide_from_customer (static, not conditional):

helpdesk/desk/src/pages/ticket/TicketCustomerTemplateFields.vue

Lines 45 to 61 in 6018181

	<div
	v-for="field in customFields"
	:key="field.fieldname"
	class="flex items-center gap-4"
	>
	<span class="w-[150px] shrink-0 text-p-sm text-ink-gray-5">{{
	field.label
	}}</span>
	<span
	class="flex-1 truncate rounded border border-outline-gray-2 bg-surface-base px-2 py-1 text-p-sm"
	:class="
	ticket.data[field.fieldname] ? 'text-ink-gray-9' : 'text-ink-gray-4'
	"
	>
	{{ ticket.data[field.fieldname] || "—" }}
	</span>
	</div>

HD Ticket Template Field child doctype has no depends_on/conditional column — only fieldname, required, hide_from_customer, url_method, placeholder.

Example
Template has fields for both "Category A" and "Category B" flows gated by a custom_category Select. Standard DocType depends_on: eval:doc.custom_category == "..." is set on the fields, but portal doesn't evaluate depends_on at all (Desk-only JS engine), so customer always sees all fields from the template, empty ones included.

Ask
Add a depends_on (eval expression) field to HD Ticket Template Field, evaluated client-side in TicketCustomerTemplateFields.vue (and ideally TicketNew.vue for creation) same way hide_from_customer is checked now — doc. scoped to ticket.data.

Note
HD Ticket Template doctype is flagged "description": "This doctype will be deprecated in the future" (

helpdesk/helpdesk/helpdesk/doctype/hd_ticket_template/hd_ticket_template.json

Line 7 in 6018181

"description": "This doctype will be deprecated in the future",

). TicketNew.vue (creation form) uses the same hide_from_customer filter and isn't the concern here, fields there are inputs, not a display of an already-submitted ticket, so an unfilled irrelevant field there doesn't read as noise. This issue is specifically about the post-creation detail view.
