Hi Prof @damithc and @ang-zeyu, I'm interested in working on this feature. According to #1332, seems like nested dropdown is still relevant and a nice to have feature. I was thinking of creating a separate component for the nested dropdown say something like <submenu>.

For exmaple:

<dropdown>
    <li>...</li> // normal dropdown item
    <li>...</li>
    <submenu>
        <li>...</li> // nested dropdown item
        <li>...</li>
    </submenu>
</dropdown>

Is this approach recommended for creating a sub-menu item inside a dropdown?

No objections from me @jonahtanjz

sounds good @jonahtanjz

wonder if we could / should do

<dropdown>
    <li>...</li> // normal dropdown item
    <li>...</li>
    <dropdown>
        <li>...</li> // nested dropdown item
        <li>...</li>
    </dropdown>
</dropdown>

as well. less syntax to remember 🙂
