I want to explain how the reefLESS Admin Panel Grid works.
At first, want to remind that you have an abilities to edit some data though grid directly.
Lets take "Listing Plans" for example:

You see tooltip (Click here to edit) when mouse over the editable field.
- One click and you have abilities to edit, see example:

- just fill in new value and click CTRL+Enter or just unfocus (click on any other page/grid place) this field to save the changes.
That all, new value has been saved.
Let me know if you still have any questions.
