Longs to regularly display options: easy! (5)
I believe the answer is:
pines
'longs' is the definition.
('pine' can be a synonym of 'long')
'to regularly display options easy' is the wordplay.
'to regularly display' means one should take alternating letters.
'options'+'easy'='optionseasy'
The alternating letters of 'optionseasy' are 'PINES'.
(Other definitions for pines that I've seen before include "Yearns for the conifers" , "Coniferous trees" , "Longs for or languishes" , "Longs for evergreen trees" , "Yearns for evergreen trees?" .)
