i want to use fabrik to maintain a (fabrik) list of items (pricing rules in my case). and when i open the form for that item, i present the user with a totally custom ui that can present a more user friendly way than a tradisional 'form' to populate the form data. i tried using a php list plugin to call the .php script that implments the custom data-input approach, but it seems to run outside of joomla and i can't easily get it to run within to joomla/component framework. i also need to put an 'exit;' on the end or it doesn't show any ui. php list plugins are meant to be run in the background it seems, not to present a ui. which is a good use-case. so i think the best approach would be to create a custom tmpl that does this. does that sound like the right approach?
