Brain teaser

[Guest]

Anyone got any ideas about the following.

I have a table of keywords. The keywords can be 3 levels deep so the table
has 3 columns Tier1, Tier2, Tier3. Tier1 is always present but Tier2 and/or
Tier3 may not be. If Tier2 is blank, Tier3 must be blank. I know this is not
normalized.

The user will be able to drill down to the lowest level. ie. I present all
unique Tier1 keywords and a "+" if there are multiple Tier2 for that Tier1.
Then on Tier2 I do the same.

Now the tricky part. I'd like to give the user the option of selecting at
the lowest Tier level directly e.g.
Software-MSOffice--Powerpoint
The user can select 'Powerpoint' directly without having to drill thru
Software and MSOffice. The problem is the lowest Tier can have duplicates e.g.
Hardware-Laptop-Display
Hardware-Computer-Display

I have 95% of this coded and working, the above is the only part I'm unsure
about. I'm thinking I'd show all unique lowest level keywords, then a "+" if
there were duplicates.
The most important requirement of this facility is that it must take the
minimum number of keystrokes to select the keyword.

My first thought is that if the user decides that they to select from Tier 3
first, then you would show them a list of unique values from the Tier 3
field. Then, when the user makes a selection from the Tier 3 list,
immediately populate another list or combo box with a list of unique values
from the Tier 2 field. If the user selects a value from the Tier 2 list then
populate still another list or combo box with the unique list of values from
the Tier 1 field.

Just thinking off the top of my head. Most of the time this is not worth
much LOL.
