I'm new to forms but hoping someone will be able to give me a pointer on how to achieve this.
SP16 on prem, no farm access.
List A is a list of job vacancies.
List B is a secondary secured list to track applications (List A is open and can't contain the more sensitive application details).
Items in List A expire after two weeks and List B has a lookup column to only show the active vacancies in List A.
There is a button on the page holding the webpart, this link is to the new form on list B that shows the active vacancies in a dropdown.
What I'd like to do is have a button on the List A view form that links to a new item form in List B with the current item preselected in an input.
So rather than a user having to view the List A item, close it, click the apply button, then find the item to select to apply for; they can hit an "Apply for this item" button and go to a form with the ID already there.
Hope that was clear 🙂
