Event creation modal

Use the popup to show a modal with an add/edit form for event creation and/or update. The popup can be easily set up to be shown right in the middle of the screen, top, bottom or anchored to the newly added event. Check out the different display modes and play around with the different configurations.

You have full control over what is shown within the popup. Use Mobiscroll form elements or any components that you are already using throughout your application.
