Remove select options from display when particular select option is not selected

I have created two select options drug 1 and drug 2

dbc.Label("Select drug1:"),
    dcc.Dropdown(id="drug1_selecter", options=drug1_options, multi=True, placeholder="All"),
    dbc.Label("Select drug2:"),
    dcc.Dropdown(id="drug2_selector", options=drug2_options, multi=True, placeholder="All"),

In the app callback only if the x_gene_selector or y_gene_selector is “Delta Emax” or “Delta IC50”, I want the above two select options to appear otherwise I don’t want them in the display.

Thank you
