I am a beginning web developer and I was wondering if anyone had any ideas on this. I saw this on a page I frequent at http://poe.trade
which is an item trading site for a game I play often. On that page you can search for an item based on the "mod's" it has. The page starts off with a single drop down box and you can start typing in a "mod" and it will autofill from available mods to pick from. Once selected you can add values into other text boxes that go along with that mod that you are searching on.
If you want to add mods to search on you hit the "Add Mod" button and another set of those controls appear which you can continue to fill out. You can add as many mods as you want to narrow down the results. That's almost exactly the type of thing I am wanting to do on my own site. I wont be doing searches, just letting people add as many "items" to a list as they want and fill in associated info for each items, than submit the list in an email.
Can anyone give me a nudge in the right direction as to what I should be searching for out there, or any hints on how this is done? This might (read "probably") be way out of my skill level, but I saw that and thought it was a very slick way of doing that!
Edit: I guess I should mention that my site is on IIS and uses ASPX pages. I know VB and not c# but if I could just be pointed in the right direction it would be helpful.
