Add a editable Field in footer of grid

(so far, I create a button on the grid, click the button and call a control panel to edit the field content. )

But I prefer to add an editable field on the footer(header), when the user input or delete the remarks, will be saved automatically.
Is it possible to add an editable field in the footer of the grid?

Not by default settings. You can hack into the code using Javascript, but I don’t recommend that.

Thank you for your reply. I got it.

Try this, works for me, on Footer event

Thank you so much for this code. Really helpful.
