Sub Categories

I see that the componet allows for unlimited categories,but can you add sub categories to the parent categories? I need this feature so that i can add parts and accessory listings to the componet.I'am currently using another componet for vehicle listing which iliked but it will not allow for sub-cats. Would be willing to pay tohave this feature added tothe componet if it is not already available.
Thank you

Hi Murphy.
Sorry in my component no have sub categories ....And I don't understand what for are necessary a sub category?(For example: You can create Category PARTS)
This component was created for Vehicles sale.

I was resdy to buy your componet, but now i guess i will
not.Just so you understand Parts and accessories have MANY SUB Caregories such as : Engine parts, lectrical parts, Transmission parts ECT.Any site which is offering advertising for vehichles should also offer itsuser the ability to sell parts and accessories for these vehicles.( this maybe an American thing, but this is what i need)
I did offer to pay for this feature but you did not even address this. I have now bought and paid for every every componet made for Joomla for this purpose and now will have to find a different CMS plateform to make my project work.( Note to Programer, Auotstand will allow sub categories, but notPaid ads, Ez Auto allows paida Ads but not Sub categories ALL I WANT IS ONE THAT WILL DO BOTH)

It very much will complicate a component and it will be not good.
Therefore I also don't want to make such changes to a component....more correctly a write separate component on PARTS which will be adhered to component EXP Autos Pro.

I did offer to pay for this feature but you did not even address this.

This time I no have time for create this only for you....
This time all time I update EXP Autos Pro component for new version and update component for Joomla CMS v1.6 .

Sale of Vehicles and auto spare parts very strongly differ, therefore it is necessary to use 2 components.
