Hi,
I have a custom entity to store 'Industry Sectors' (I can't use categories, because N:N relationships aren't available for them).
The sectors entity is related to Accounts with a N:N relationship, such that multiple sectors can be assigned to an account. The sectors entity is self-referencing such that a hierarchy of sectors can be created.
I then have a sub-grid on the accounts form to enable the user to add industry sectors to the account.
This all works great, but the issue I have is that the sector list is quite long and goes 4 levels deep. What I want to be able to do is for the user to initially select from a list of level 1 sectors then see level 2 options for that sector etc. through to the lowest 4th level. At any point they may add the sector to the account as they may not necessarily know to the 4th level of granularity what that account does.
Is there a way to do this, i.e., add drill-down style functionality to the selection? I know the user could search for the sector, but that would require that they know specifically how they are named and the list is too long to practically browse without employing a hierarchy approach.
Any thoughts?
Many thanks!
