Hi Jerome thanks for the reply
Could you explain me a little better, I have reviewed the massive actions to see to implement what you indicate.
As far as I understood and with what I review, I could perform an action on the user, when the user updates their data, on the custom field that you mention and the action would be to change the user group.
First problem, I do not see in the action where to indicate that the seller user group (group of all sellers of the site) should be removed.
On the other hand, I understand that for this action to be carried out, the user should edit his account, his user account (not the seller's), modify the custom field (checkbox) and save the changes, this would be quite complex, it would also be important a confirmation, which in this way I don't think there is.
The ideal would be a button in the seller panel that when clicking, shows a confirmation message before deleting the seller user group to the user or at least unpublishing the seller and their products. Is this possible to do with what they currently have hikashop?
