Jotform Sign: How to allow draw only in the Signature element?

Bonjour j'ai créé un jotform sign via un PDF existant, ça fonctionne bien par contre je vois que le client a le choix de signer avec "Nom et prénom" ou de dessiner. Je voudrais forcer la case en mode dessin uniquement car l'organisme qui nous demande les certificats signés n'acceptent pas les signatures avec nom prenom, uniquement avec le dessin de la signature. Avez vous une solution ?

Hello ecoloclast

Thanks for reaching out to Jotform Support. Unfortunately, our French Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in French, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Unfortunately, disabling the Type option in the Signature element of the Sign Document is currently not possible. While the feature you’re looking for isn’t currently available, rest assured we’re always working to add new services and features to Jotform. I've gone ahead and escalated your request to our developers. When or if it's implemented depends on their workload, how viable it is, and how many other users request it. If there are any updates, we’ll circle back to this thread and let you know. 

Reach out again if you have any other questions.
