I want to add a button and clickable event inside the node is there any way to do it?

```auto
digraph structs {
    node [shape=plaintext]
    struct1 [label=<
<TABLE BORDER="0" CELLBORDER="1" CELLSPACING="0">
  <TR><TD>left</TD><TD PORT="f1">mid dle</TD><TD PORT="f2">right</TD></TR>
</TABLE>>];
    struct2 [label=<
<TABLE BORDER="0" CELLBORDER="1" CELLSPACING="0">
  <TR><TD PORT="f0">one</TD><TD>two</TD></TR>
</TABLE>>];
    struct3 [label=<
<TABLE BORDER="0" CELLBORDER="1" CELLSPACING="0" CELLPADDING="4">
  <TR>
    <TD ROWSPAN="3">hello<BR/>world <BUTTON TYPE="BUTTON" ONCLICK="callBack()">HELLO BUTTON</BUTTON> </TD>
    <TD COLSPAN="3">b</TD>
    <TD ROWSPAN="3">g</TD>
    <TD ROWSPAN="3">h</TD>
  </TR>
  <TR>
    <TD>c</TD><TD PORT="here">d</TD><TD>e</TD>
  </TR>
  <TR>
    <TD COLSPAN="3">f</TD>
  </TR>
</TABLE>>];
    struct1:f1 -> struct2:f0;
    struct1:f2 -> struct3:here;
}

```

Short answer - Graphviz does not support this  
Longer answers, if you are willing to fiddle around:

- If you can use non-HTML records, Marc’s answer may work for you (uses class attribute): [Can I make a Digraph node interactive](https://forum.graphviz.org/t/can-i-make-a-digraph-node-interactive/503)
- If HTML-record shape is necessary, maybe this “kludge” will work:
  - use/abuse the **href** attribute to insert a version of your javascript code
  - postprocess the SVG output to fix the href-related text (using awk, python, sed, …)

```auto
digraph structs {
    node [shape=plaintext]
    struct3 [label=<
<TABLE BORDER="0" CELLBORDER="1" CELLSPACING="0" CELLPADDING="4">
  <TR>
    <TD ROWSPAN="3" href="!!alert('done')">hello<BR/>world</TD>
    <TD COLSPAN="3">b</TD>
    <TD ROWSPAN="3">g</TD>
    <TD ROWSPAN="3" href="!!alert('hello there')">h</TD>
  </TR>
</TABLE>>];
}

```

postprocessing:

```auto
gawk '
  /href="!!/{
    sub("><.*!!"," onclick=\"");
    sub(/xlink[^>]*/,"")
  }
 $0=="</a>"{next}
{print}' myfile.svg

```

Ugly, but seems to work
