Hi,
I’m extending the cornerstone elements with a custom element.
Which includes the Multi Choose control type.
The list shows up fine, but I’m not able to deselect an element after I’ve saved the page.
If anybody knows what’s going on, a bit of help would be much appreciated.
Hey,
Thank you for writing in!
if you could post some logins details in a secure note and we`d be happy to take a look.
P.S: You can search by “secure note” on this article if you don`t know about this: https://theme.co/apex/forum/t/themeco-support-overview/288
Hi again,
Thanks for looking in to it. 
Hi There,
Thank you for the credentials. Regretfully, this particular issue is outside the scope of our support as this is not related to an issue with the theme and instead has to do with your customization of it. As such, you will need to investigate this particular issue on your own or seek help from a developer should you not feel comfortable making these changes yourself. We do have an in-house custom development team that offer paid services, who may be able to assist. They can be contacted at pinnacle@theme.co if this is of interest to you. If you have any further questions about the theme, we are more than happy to provide you with assistance on these inquiries.
Thank you for your understanding.
