RowReorder, disallow drag and drop ?

korey03

Hello,
I'm using RowReorder extention and I want a row on top that can't be drag and drop then prevent an other row to replace it.
Is that possible?

See if this thread helps. Its not a trivial task but possible. The thread keeps the bottom row at the bottom. Try changing the last example in the thread to keep the row at the top.

Thank you, that helped me a lot.

I'm looking for a way to save the table state before moving a row and if a row is moved to the first one then we go back to its previous state.

I tried something. Well... I don't understand, the first time when I drop the fourth row for example on the first one it works but not the second times.

Without digging into your code I'm not sure what is going on either. One problem I noticed is you aren't disabling the top row from being moved. I fixed it here by changing your if statement to if (rowData[1] === 'owner') {, see here:

You don't need to clear the rows and use rows().add() to re-add them. You can use the data that is available to the row-reordered event to revert the order. Basically you can apply the oldData value to each row that was reordered. Here is you example updated:

Its actually a much simpler solution than the one I posted. In that example I wanted to swap the static row with the one that was dragged and dropped. You just want to revert back.

I figured out where my mistake was.

Thank you so much for your support.
