His poetry is traditionally confessional, the narration realistic and satirical while the form rests on traditional meter with romantic images and everyday reality. Also well known are his epigrams. Menart complemented original poetry by translating foreign language literature. Slovenes have to thank him for, among others, the excellent translations of Shakespeare's Sonnets, Byron's, Burns's and Prévert's poetry and Villon's Collected Works. He also translated English Renaissance plays such as Volpone by Jonson and Doctor Faustus by Christopher Marlowe. Although mainly known as a poet and translator, Menart also wrote scripts for puppet and documentary films and television plays. He was also the first in Slovenia to publish a CD audiobook, with his poems largely interpreted by him himself. In 1975, his poem "Homeland" (), translated by the Croatian poet Zvonimir Golob, was used as lyrics for the song "Domovina" sung by the Croatian rock and folk musician Drago Mlinarec.
