WordPress Custom Fields by category

let’s say I have 100 categories and each has 10 custom fields for it self,for example :
category Computer : Cpu – Hard – Ram – …
category TV : resolution – inch – usb support – …
…

now I want the editor only can see related custom fields to post(ex. computer) , I don’t want them to see like 1000 custom fields and tries to find the related custom field to fill in, it will take for ever !

I’m making my own theme and can do what ever change that is needed !!
I couldn’t find any plugin for this !

thanks in advance .

Try using magic fields. It will let you create a custom panel for each category, where you can specify just the custom fields needed for that category. It allows you to present it all in a very user friendly way as well, as well as manuy, many, many other cool things. The plugin will change your life if you do this sort of thing often, using wordpress as CMS!
