Hi! I am working with the ShowDropArea property. With an external button, I change the state of the boolean value. And the column to be dropped is frozen after hiding and showing the Drop Area Again.
You can see the behavior following the next steps.
1. There is a toggle button I change the status of the ShowDropArea property(to show and hide the Drop Area).
2. At first render no problem dropping the columns, once I click the button to hide the drop area and click again to show the Drop Area and tries to drop another column the column gets frozen in the drop area.
I am attaching the project in the Grouping folder is the page with the demo, and also there is a gif in the rar.
