Custom Attribute
The custom attributes were developed to provide users greater flexibility and to satisfy their need to create a various Unit extensions.
After the user select the Custom Attribute a Unit section automatically shows before the Description. The user is then given the choice of choosing from already defined units, performing a simple name search if the list is too long, or creating a new unit extension if necessary.
Let's follow an example where the user wants to establish attributes for describing Color Temperature in Kelvins
Let's start by creating a new attribute with the name "Color Temperature" and choosing a Custom from the type drop-down selection. After creating the attribute, let's go to its edit page and under the Unit field lets select the letter "K" created as a reference unit for Kelvins.
Now, our system will save your Color Temperature attributes as a number with Kelvins as their measurement unit.
