Hi everyone,

I’m trying to edit the dashboard header in OJS 3.5.

In /lib/pkp/templates/layouts/backend.tpl, I found the following code, which displays the user and notification icons in the top right corner:

{if $currentUser}{call_hook name=“Template::Layout::Backend::HeaderActions”}
< top-nav-actions >< / top-nav-actions >
{/if}

I’d like more control over what appears inside.

Could anyone tell me where this component is defined or which file I should edit to customize it?

Thanks in advance!
