I've built a custom sign up form in webflow and verified it through memberstack, however, I can't seem to get the dropdown list to work where a member chooses their membership level when signing up.

For each dropdown choice, I've added the membership id as the value but I'm not sure where to put "data-ms-membership". 
Warren not totally clear on this. Are you saying that the road block is... 

  1. With populating the dropdown items with the name of each membership?
  2. Or a user can choose the membership via your dropdown but when signing up they are being added to the membership they selected via the dropdown? 
  3. ..or am I totally misunderstanding 😅
 ChrisDrit  thanks for the quick reply and sorry for taking so long to get back to you. I checked with memberstack and they don't currently support this natively (which blows my mind) so I think the solution would have to entail some custom JS as you suggested. I'll report back if I ever get around to implementing it.
 ChrisDrit  thanks for the reply. I have 3 membership levels (Basic, Pro, Premium). 
I'd like to have one sign up form, and on that signup form, I'd like for the member to be able to choose which membership they will be signing up for.

Right now, when I attempt to sign up, it always goes to the default membership in Memberstack which tells me that it's ignoring that membership level field. Here is a picture of the form...

Hopefully, that makes more sense 😀
