HI There

For populating a native project task field on a vendor bill, is there a way to restrict the options presented in the drop down using a script?

I'm imagining it would have to be a client script since this action takes place in the browser.

What I am thinking of is, if the item selected is "item A", then the tasks available to code to are:

task 1A,

task 2A,

task 3A

If the item selected is 'item B', then the project tasks available are :

task 1B,

task 2B

task 2C

Essentially, what i am after is narrowing down the list of project tasks for a project that appear at the line level based on the item selected.
