Enhancement: trigger multiple events

[euri10]

Summary

from the docs here https://htmx.org/headers/hx-trigger/

Multiple Triggers
If you wish to invoke multiple events, you can simply add additional properties to the top level JSON object:

HX-Trigger: {"event1":"A message", "event2":"Another message"}

You may also trigger multiple events with no additional details by sending event names separated by commas, like so:

HX-Trigger: event1, event2

Using events gives you a lot of flexibility to add functionality to normal htmx responses.

I dont see a way to achieve that, is that possible ?
adding manually the headersshould solve it, for instance this is ok, the commented part is what I would have originally written, passing headers works fine

        return HTMXTemplate(
            template_name="rbac_user_role_permissions.html",
            context={"user_role_permissions": user_role_permissions},
            # # trigger_event="update_user_roles,update_role_permissions",
            # after="swap",
            headers={"HX-Trigger-After-Swap": "update_user_roles, update_role_permissions"}
        )

if not im fancy implementing it since I selfishly need it :)

question is it possible to make that backward compatible, especially given trigger_event parans and after are linked one to another

        trigger_event="showMessage",  # trigger event name
        params={"alert": "Confirm your Choice."},  # parameter to pass to the event
        after="receive",  #  when to trigger event,

alright I asked on the htmx discord how django does this to get a feell if we could take inspiration from them :

https://django-htmx.readthedocs.io/en/latest/http.html#django_htmx.http.trigger_client_event

the interesting bit is here:

Calling trigger_client_event multiple times for the same response and after will update the appropriate header, preserving existing event specifications.

that fonction takes the response as a parameter, modifies the headers according to pretty much the same kwargs we already have, and return the response.
so the design is quite different

I'm not sure I dont prefer to pass headers manually
