I have created a custom filter for the link existing record drop down for a subpanel called brand on the contacts module. It is a filter to only show brands that relate to the same company that the contact relates to. I have done this like so: custom/modules/BRD_Brand/clients/base/views/panel-top-for-contacts/panel-top-for-contacts.php
This is done in the same way that the cases module does it with the contacts subpanel 'link existing record' drop down.
I am wondering if it is possible to make this filter uneditable by users?
Thanks for any help.
