How to hide node/edge on click ?

[akwawa]

Hello,

I have a digraph like this :

digraph "test" {
        label="test"; fontsize=20; pad=0.5; bgcolor="#2e3e56";
        node [shape="record", width="0.6", style="filled", fillcolor="white", color="grey", penwidth="1", label=""];
        edge [color="black", penwidth="1", fontname="Comic Sans MS"];
        A1[label="{a1|{001|002|003}}"];
        A2[label="{a2|{00Z}}"];
        A1 -> A2 [label=""];
        B1[label="{b1|{001|002|003}}"];
}

When I click on A1 or A2, I would like B2 to disappear.
What should I do ?

Thanks you for help.
