The standard nopCommerce product page does not have +/- fields to increase/decrease quantity.
Have you customized, or are you using a third-party plugin / theme?

in the product menu has a inventory section and inside there is a box for "allowed quantities" there ; i can change it with 1-2-3-4-5... but i cannot use 0.5-1-1.5 ....


i tried with ,;.: symbols to seperate the numbers but not acceptable.

im the user of the nopCommerce. We pay the seller to build a site for us . i dont know how they do it or used the 3rd party . when i asked them they also cannot find a solution for us thats why im here.

Fractional quantities is custom.  If they built that for you, then they should be able force the increment/decrement to be based on 0.5 rather than 0.1

(Entering "allowed quantities" probably won't work well with increment/decrement feature.)

Thanks for the reply im going to search more . if i found a solution i will write back here .

best regards

. couldnt find any solution .
