Thank you for answer!
Before posting I tried these solutions.
If i use "BLURB", this is visible on store front, under the product image. I not need see here, because some text/information is too long. But is a very good solution if is not visible here, and is visible only under the PRICE.
If i use ckeckbox/selectbox/radio, is visible the radio button/check button or field box. I don't need see this. It is not necessary for the buyer to select. How can hide this? The same, is a good solution, if only the text/information show. I tried to use hidden files, but it is only visible in the cart page.
I need a simple solution to use this information for some product, not for all.
My ideea is to create a new field dedicated for this in Product Summary--->General. Idon't know how can i made this.
The same i create a html block with this information, but i can't insert in this place, because is non editable or have default settings. This way work, but the text show above to LATEST PRODUCTS or the image.
If you have time to find a solution, please post it. Maybe other users need this solution.
Thank you!
