There is no functionality enabling you to control the order in which your products will display in Productspec.
Productspec users/members use filters to easily find the relevant products via attributes like:
- Secondary and Tertiary Categories
- Appraisals or CodeMark Certification
- CAD and BIM files with any of the permitted file types: 3ds, 3dm, dwf, dxf, dwg, gsm, ies, max, mcd, mod, pdf, pln, rvt and rfa
However, if you would like your products to appear at the top of relevant categories, and ordered first when viewing all your products, you can take advantage of the Featured Products functionality.
