问题
I'm trying to do something like below:
Scenario 1: User will drag and drop List 1 from left side to right side.
Scenario 2: Again, User will drag list 2 to right side, when that dragging item hover on list 1, have to show drop zones to drop that list 2 item here.
Finally, List 1 and List 2 both will be placed like left and right side.
With React Dnd, Is this achievable? and I tried this it works only while dragging. https://stackblitz.com/edit/react-pctpdh
I'm able to show a drop area while dragging, it shows every time, but I need to show that drop area only hover on some item.
Below is the sample work, I have to achieve:
Need to show placeholder to drop an item while hover other items to drop. (Need to Create dynamic drop targets while mouse hover some item)
I need a help on this to achieve this feature.Any idea on this really commendable.
回答1:
I saw the code snippet and i added some new code that replicates your desired behavior.
The idea is to create a separate component to handle drop actions, that can be reused when is needed. In this particular case, I choose to use the component inside your ListItem component to create two drop zones on both sides.
Here is the updated code: https://stackblitz.com/edit/react-pctpdh
