How can I dynamically fill a dropdown list in a Tool Part panel of a SharePoint 2013 app part?
What I want to achieve:
- User checks a checkbox
- Dropdown appears
- The list items in this dropdown are set in the server side i.e. either dependent on user's input for other elements or on the specific user's permissions
Your help is really appreciated! I need to come up with a solution as soon as possible, so any guidance on how to approach this will be truly appreciated.
