Create the first product with its corresponding attributes and then use it as a template and Copy it(in admin>mcatalog>manage products) for next products
I don't see the menu options you mentioned. I am using nopCommerce 2.2.
In the administration section I can go to Catalog > Products > Manage Products. But I don't see any way to copy a product or set one as a template.
Sorry, I forgot to mention that you have to proceed to edit the product you want to copy: Catalog > Products > Manage Products >Edit (product you want to copy). See example of demo admin here.
I was trying to change the multilineTextbox in Nop 1.90 so that it would be a longer width and less in height (550, 100). See my changes below to the Modules/ProductAttributes.ascx.cs file
It does not seem to change anything in the display.
case AttributeControlTypeEnum.MultilineTextbox: { var txtAttribute = new TextBox(); txtAttribute.ID = controlId; txtAttribute.TextMode = TextBoxMode.MultiLine; txtAttribute.Width = this.SettingManager.GetSettingValueInteger("ProductAttribute.MultiTextbox.Width", 500); txtAttribute.Height = this.SettingManager.GetSettingValueInteger("ProductAttribute.MultiTextbox.Height", 100); divAttribute.Controls.Add(txtAttribute); }
