DashDataTable with Dropdowns

Hello, I create DashDatatable, I am creation conditional_dropdown but I would like to give it options all values except 1st column value(In picure you can understand better way), in addition when I change value of View column, it removes dropdowns but it fixes value of dropdown selected before, how can i clear it?

hi @ShamkhalHajiyev
Thank you for posting the question.
It would be a lot easier to help you if we could replicate your code locally on our computer. Could you please share a dataset example with us, and put your code in preformatted text like this:

from dash import Dash
import plotly.express as px

app = Dash()
