Drawer behind counter containing wide fabric (5)
I believe the answer is:
twill
'fabric' is the definition.
(twill is a kind of fabric)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for twill that I've seen before include "Fabric with distinctive weave" , "Fabric woven to produce a surface of diagonal parallel ridges" , "Stuff" , "Strong woven fabric" , "Strong ridged fabric" .)
