Id like to use product tags as a second classification for products from the Add New Product menu, however the product tag option in its default state is not reliable.
Id like to customise it so that I could select from a complete list with checkboxes as is done with categories. The product tags populate one of my dropdown menus, so they need to be consistent, created in the Tag menu, much like Categories and not created on the fly, duplicated, or be similar to others, as is the case with Tags currently.
I have used some code previously which created a tag cloud to choose from, but it was never a complete list and not ideal.
Can this be done? And is it the best option for achieving a second product classification from the product page. Im trying to avoid plugins.
